+### How to choose `m` and `ef_construction` for `IVF_HNSW_*` index?
+
+`m` determines the number of connections a new node establishes with its closest neighbors upon entering the graph. Typically, `m` falls within the range of 5 to 48. Lower `m` values are suitable for low-dimensional data or scenarios where recall is less critical. Conversely, higher `m` values are beneficial for high-dimensional data or when high recall is required. In essence, a larger `m` results in a denser graph with increased connectivity, but at the expense of higher memory consumption.
+
+`ef_construction` balances build speed and accuracy. Higher values increase accuracy but slow down the build process. A typical range is 150 to 300. For good search results, a minimum value of 100 is recommended. In most cases, setting this value above 500 offers no additional benefit. Ensure that `ef_construction` is always set to a value equal to or greater than `ef` in the search phase

-LanceDB provides support for full-text search via Lance (before via [Tantivy](https://github.com/quickwit-oss/tantivy) (Python only)), allowing you to incorporate keyword-based search (based on BM25) in your retrieval solutions.
-
-Currently, the Lance full text search is missing some features that are in the Tantivy full text search. This includes query parser and customizing the tokenizer. Thus, in Python, Tantivy is still the default way to do full text search and many of the instructions below apply just to Tantivy-based indices.
-
-
-## Installation (Only for Tantivy-based FTS)
+LanceDB provides support for full-text search via Lance, allowing you to incorporate keyword-based search (based on BM25) in your retrieval solutions.
 
 !!! note
-    No need to install the tantivy dependency if using native FTS
-
-To use full-text search, install the dependency [`tantivy-py`](https://github.com/quickwit-oss/tantivy-py):
-
-```sh
-# Say you want to use tantivy==0.20.1
-pip install tantivy==0.20.1

 It would search on all indexed columns by default, so it's useful when there are multiple indexed columns.

+Passing `fts_columns="text"` if you want to specify the columns to search.
 
 !!! note
     LanceDB automatically searches on the existing FTS index if the input to the search is of type `str`. If you provide a vector as input, LanceDB will search the ANN index instead.
 
 ## Tokenization
-By default the text is tokenized by splitting on punctuation and whitespaces and then removing tokens that are longer than 40 chars. For more language specific tokenization then provide the argument tokenizer_name with the 2 letter language code followed by "_stem". So for english it would be "en_stem".
+By default the text is tokenized by splitting on punctuation and whitespaces, and would filter out words that are with length greater than 40, and lowercase all words.
 
-For now, only the Tantivy-based FTS index supports to specify the tokenizer, so it's only available in Python with `use_tantivy=True`.
+Stemming is useful for improving search results by reducing words to their root form, e.g. "running" to "run". LanceDB supports stemming for multiple languages, you can specify the tokenizer name to enable stemming by the pattern `tokenizer_name="{language_code}_stem"`, e.g. `en_stem` for English.
 
-=== "use_tantivy=True"

-    ```
-
-=== "use_tantivy=False"
-
-    [**Not supported yet**](https://github.com/lancedb/lance/issues/1195)
+For example, to enable stemming for English:
+```python
+table.create_fts_index("text", use_tantivy=True, tokenizer_name="en_stem")
+```
 
 the following [languages](https://docs.rs/tantivy/latest/tantivy/tokenizer/enum.Language.html) are currently supported.
 
-## Index multiple columns
+The tokenizer is customizable, you can specify how the tokenizer splits the text, and how it filters out words, etc.
 
-If you have multiple string columns to index, there's no need to combine them manually -- simply pass them all as a list to `create_fts_index`:

-

- .limit(20)
- .to_list())
-```
-
-!!! note
-    If you wish to specify an ordering field at query time, you must also
-    have specified it during indexing time. Otherwise at query time, an
-    error will be raised that looks like `ValueError: The field does not exist: xxx`
-
-!!! note
-    The fields to sort on must be of typed unsigned integer, or else you will see
-    an error during indexing that looks like
-    `TypeError: argument 'value': 'float' object cannot be interpreted as an integer`.
-
-!!! note
-    You can specify multiple fields for ordering at indexing time.
-    But at query time only one ordering field is supported.
-
-
 ## Phrase queries vs. terms queries
 
 !!! warning "Warn"
     Lance-based FTS doesn't support queries using boolean operators `OR`, `AND`.
 
 For full-text search you can specify either a **phrase** query like `"the old man and the sea"`,
-or a **terms** search query like `"(Old AND Man) AND Sea"`. For more details on the terms
+or a **terms** search query like `old man sea`. For more details on the terms
 query syntax, see Tantivy's [query parser rules](https://docs.rs/tantivy/latest/tantivy/query/struct.QueryParser.html).
 
-!!! tip "Note"
-    The query parser will raise an exception on queries that are ambiguous. For example, in the query `they could have been dogs OR cats`, `OR` is capitalized so it's considered a keyword query operator. But it's ambiguous how the left part should be treated. So if you submit this search query as is, you'll get `Syntax Error: they could have been dogs OR cats`.
-
-    ```py
-    # This raises a syntax error
-    table.search("they could have been dogs OR cats")
-    ```
-
-    On the other hand, lowercasing `OR` to `or` will work, because there are no capitalized logical operators and
-    the query is treated as a phrase query.
-
-    ```py
-    # This works!
-    table.search("they could have been dogs or cats")
-    ```
-
-It can be cumbersome to have to remember what will cause a syntax error depending on the type of
-query you want to perform. To make this simpler, when you want to perform a phrase query, you can
-enforce it in one of two ways:
-
-1. Place the double-quoted query inside single quotes. For example, `table.search('"they could have been dogs OR cats"')` is treated as
-a phrase query.
-1. Explicitly declare the `phrase_query()` method. This is useful when you have a phrase query that
-itself contains double quotes. For example, `table.search('the cats OR dogs were not really "pets" at all').phrase_query()`
-is treated as a phrase query.
-
-In general, a query that's declared as a phrase query will be wrapped in double quotes during parsing, with nested
-double quotes replaced by single quotes.
-
-
-## Configurations (Only for Tantivy-based FTS)
-
-By default, LanceDB configures a 1GB heap size limit for creating the index. You can
-reduce this if running on a smaller node, or increase this for faster performance while
-indexing a larger corpus.
-
+To search for a phrase, the index must be created with `with_position=True`:
 ```python
-# configure a 512MB heap size
-heap = 1024 * 1024 * 512
-table.create_fts_index(["text1", "text2"], writer_heap_size=heap, replace=True)
+table.create_fts_index("text", use_tantivy=False, with_position=True)
 ```
+This will allow you to search for phrases, but it will also significantly increase the index size and indexing time.
 
-## Current limitations
 
-For that Tantivy-based FTS:
+## Incremental indexing
 
-1. Currently we do not yet support incremental writes.
-   If you add data after FTS index creation, it won't be reflected
-   in search results until you do a full reindex.
+LanceDB supports incremental indexing, which means you can add new records to the table without reindexing the entire table.
 
-2. We currently only support local filesystem paths for the FTS index.
-   This is a tantivy limitation. We've implemented an object store plugin
-   but there's no way in tantivy-py to specify to use it.
+This can make the query more efficient, especially when the table is large and the new records are relatively small.

+# Full-text search (Tantivy-based FTS)
+
+LanceDB also provides support for full-text search via [Tantivy](https://github.com/quickwit-oss/tantivy), allowing you to incorporate keyword-based search (based on BM25) in your retrieval solutions.
+
+The tantivy-based FTS is only available in Python and does not support building indexes on object storage or incremental indexing. If you need these features, try native FTS [native FTS](fts.md).
+
+## Installation
+
+To use full-text search, install the dependency [`tantivy-py`](https://github.com/quickwit-oss/tantivy-py):
+
+```sh
+# Say you want to use tantivy==0.20.1
+pip install tantivy==0.20.1
+```
+
+## Example
+
+Consider that we have a LanceDB table named `my_table`, whose string column `content` we want to index and query via keyword search, the FTS index must be created before you can search via keywords.
+
+```python
+import lancedb
+
+uri = "data/sample-lancedb"
+db = lancedb.connect(uri)
+
+table = db.create_table(
+    "my_table",
+    data=[
+        {"id": 1, "vector": [3.1, 4.1], "title": "happy puppy", "content": "Frodo was a happy puppy", "meta": "foo"},
+        {"id": 2, "vector": [5.9, 26.5], "title": "playing kittens", "content": "There are several kittens playing around the puppy", "meta": "bar"},
+    ],
+)
+
+# passing `use_tantivy=False` to use lance FTS index
+# `use_tantivy=True` by default
+table.create_fts_index("content", use_tantivy=True)
+table.search("puppy").limit(10).select(["content"]).to_list()
+# [{'text': 'Frodo was a happy puppy', '_score': 0.6931471824645996}]
+# ...
+```
+
+It would search on all indexed columns by default, so it's useful when there are multiple indexed columns.
+
+!!! note
+    LanceDB automatically searches on the existing FTS index if the input to the search is of type `str`. If you provide a vector as input, LanceDB will search the ANN index instead.
+
+## Tokenization
+By default the text is tokenized by splitting on punctuation and whitespaces and then removing tokens that are longer than 40 chars. For more language specific tokenization then provide the argument tokenizer_name with the 2 letter language code followed by "_stem". So for english it would be "en_stem".
+
+```python
+table.create_fts_index("content", use_tantivy=True, tokenizer_name="en_stem", replace=True)
+```
+
+the following [languages](https://docs.rs/tantivy/latest/tantivy/tokenizer/enum.Language.html) are currently supported.
+
+## Index multiple columns
+
+If you have multiple string columns to index, there's no need to combine them manually -- simply pass them all as a list to `create_fts_index`:
+
+```python
+table.create_fts_index(["title", "content"], use_tantivy=True, replace=True)
+```
+
+Note that the search API call does not change - you can search over all indexed columns at once.

-# Building Scalar Index
+# Building a Scalar Index
 
-Similar to many SQL databases, LanceDB supports several types of Scalar indices to accelerate search
+Scalar indices organize data by scalar attributes (e.g. numbers, categorical values), enabling fast filtering of vector data. In vector databases, scalar indices accelerate the retrieval of scalar data associated with vectors, thus enhancing the query performance when searching for vectors that meet certain scalar criteria. 
+
+Similar to many SQL databases, LanceDB supports several types of scalar indices to accelerate search
 over scalar columns.
 
-- `BTREE`: The most common type is BTREE. This index is inspired by the btree data structure
-  although only the first few layers of the btree are cached in memory.
-  It will perform well on columns with a large number of unique values and few rows per value.
-- `BITMAP`: this index stores a bitmap for each unique value in the column.
-  This index is useful for columns with a finite number of unique values and many rows per value.
-  For example, columns that represent "categories", "labels", or "tags"
-- `LABEL_LIST`: a special index that is used to index list columns whose values have a finite set of possibilities.
+- `BTREE`: The most common type is BTREE. The index stores a copy of the
+  column in sorted order. This sorted copy allows a binary search to be used to
+  satisfy queries.
+- `BITMAP`: this index stores a bitmap for each unique value in the column. It 
+  uses a series of bits to indicate whether a value is present in a row of a table
+- `LABEL_LIST`: a special index that can be used on `List<T>` columns to
+  support queries with `array_contains_all` and `array_contains_any`
+  using an underlying bitmap index.
   For example, a column that contains lists of tags (e.g. `["tag1", "tag2", "tag3"]`) can be indexed with a `LABEL_LIST` index.
 
+!!! tips "How to choose the right scalar index type"
+
+    `BTREE`: This index is good for scalar columns with mostly distinct values and does best when the query is highly selective.
+    
+    `BITMAP`: This index works best for low-cardinality numeric or string columns, where the number of unique values is small (i.e., less than a few thousands).
+    
+    `LABEL_LIST`: This index should be used for columns containing list-type data.

       If the table does not exist an exception is raised.
 
+## Handling bad vectors
+
+In LanceDB Python, you can use the `on_bad_vectors` parameter to choose how
+invalid vector values are handled. Invalid vectors are vectors that are not valid
+because:
+
+1. They are the wrong dimension
+2. They contain NaN values
+3. They are null but are on a non-nullable field
+
+By default, LanceDB will raise an error if it encounters a bad vector. You can
+also choose one of the following options:
+
+* `drop`: Ignore rows with bad vectors
+* `fill`: Replace bad values (NaNs) or missing values (too few dimensions) with
+    the fill value specified in the `fill_value` parameter. An input like
+    `[1.0, NaN, 3.0]` will be replaced with `[1.0, 0.0, 3.0]` if `fill_value=0.0`.
+* `null`: Replace bad vectors with null (only works if the column is nullable).
+    A bad vector `[1.0, NaN, 3.0]` will be replaced with `null` if the column is
+    nullable. If the vector column is non-nullable, then bad vectors will cause an

-![Illustration](../assets/langchain.png)
+**LangChain** is a framework designed for building applications with large language models (LLMs) by chaining together various components. It supports a range of functionalities including memory, agents, and chat models, enabling developers to create context-aware applications.
+
+![Illustration](https://raw.githubusercontent.com/lancedb/assets/refs/heads/main/docs/assets/integration/langchain_rag.png)
+
+LangChain streamlines these stages (in figure above) by providing pre-built components and tools for integration, memory management, and deployment, allowing developers to focus on application logic rather than underlying complexities.
+
+Integration of **Langchain** with **LanceDB** enables applications to retrieve the most relevant data by comparing query vectors against stored vectors, facilitating effective information retrieval. It results in better and context aware replies and actions by the LLMs.
 
 ## Quick Start
 You can load your document data using langchain's loaders, for this example we are using `TextLoader` and `OpenAIEmbeddings` as the embedding model. Checkout Complete example here - [LangChain demo](../notebooks/langchain_example.ipynb)

+**phidata** is a framework for building **AI Assistants** with long-term memory, contextual knowledge, and the ability to take actions using function calling. It helps turn general-purpose LLMs into specialized assistants tailored to your use case by extending its capabilities using **memory**, **knowledge**, and **tools**. 
+
+- **Memory**: Stores chat history in a **database** and enables LLMs to have long-term conversations.
+- **Knowledge**: Stores information in a **vector database** and provides LLMs with business context. (Here we will use LanceDB)
+- **Tools**: Enable LLMs to take actions like pulling data from an **API**, **sending emails** or **querying a database**, etc.

+
+Memory & knowledge make LLMs smarter while tools make them autonomous.
+
+LanceDB is a vector database and its integration into phidata makes it easy for us to provide a **knowledge base** to LLMs. It enables us to store information as [embeddings](../embeddings/understanding_embeddings.md) and search for the **results** similar to ours using **query**. 
+
+??? Question "What is Knowledge Base?"
+    Knowledge Base is a database of information that the Assistant can search to improve its responses. This information is stored in a vector database and provides LLMs with business context, which makes them respond in a context-aware manner.
+
+    While any type of storage can act as a knowledge base, vector databases offer the best solution for retrieving relevant results from dense information quickly.
+
+Let's see how using LanceDB inside phidata helps in making LLM more useful:

+            uri="./t2mp/.lancedb",
+        ),
+        num_documents = 10
+    )
+    ```
+Check out the list of **embedders** supported by **phidata** and their usage [here](https://docs.phidata.com/embedder/introduction).
+
+Here we have used `TextKnowledgeBase`, which loads text/docx files to the knowledge base.
+
+Let's see all the parameters that `TextKnowledgeBase` takes -
+
+| Name| Type | Purpose | Default |
+|:----|:-----|:--------|:--------|
+|`path`|`Union[str, Path]`| Path to text file(s). It can point to a single text file or a directory of text files.| provided by user |
+|`formats`|`List[str]`| File formats accepted by this knowledge base. |`[".txt"]`|
+|`vector_db`|`VectorDb`| Vector Database for the Knowledge Base. phidata provides a wrapper around many vector DBs, you can import it like this - `from phi.vectordb.lancedb import LanceDb` | provided by user |
+|`num_documents`|`int`| Number of results (documents/vectors) that vector search should return. |`5`|
+|`reader`|`TextReader`| phidata provides many types of reader objects which read data, clean it and create chunks of data, encapsulate each chunk inside an object of the `Document` class, and return **`List[Document]`**.  | `TextReader()` |
+|`optimize_on`|`int`| It is used to specify the number of documents on which to optimize the vector database. Supposed to create an index. |`1000`|
+
+??? Tip "Wonder! What is `Document` class?"
+    We know that, before storing the data in vectorDB, we need to split the data into smaller chunks upon which embeddings will be created and these embeddings along with the chunks will be stored in vectorDB. When the user queries over the vectorDB, some of these embeddings will be returned as the result based on the semantic similarity with the query.
+    
+    When the user queries over vectorDB, the queries are converted into embeddings, and a nearest neighbor search is performed over these query embeddings which returns the embeddings that correspond to most semantically similar chunks(parts of our data) present in vectorDB. 
+
+    Here, a “Document” is a class in phidata. Since there is an option to let phidata create and manage embeddings, it splits our data into smaller chunks(as expected). It does not directly create embeddings on it. Instead, it takes each chunk and encapsulates it inside the object of the `Document` class along with various other metadata related to the chunk. Then embeddings are created on these `Document` objects and stored in vectorDB.
+
+    ```python
+    class Document(BaseModel):
+        """Model for managing a document"""
+
+        content: str # <--- here data of chunk is stored 
+        id: Optional[str] = None
+        name: Optional[str] = None
+        meta_data: Dict[str, Any] = {}
+        embedder: Optional[Embedder] = None
+        embedding: Optional[List[float]] = None
+        usage: Optional[Dict[str, Any]] = None
+    ```
+
+However, using phidata you can load many other types of data in the knowledge base(other than text). Check out [phidata Knowledge Base](https://docs.phidata.com/knowledge/introduction) for more information.
+
+Let's dig deeper into the `vector_db` parameter and see what parameters `LanceDb` takes -
+
+| Name| Type | Purpose | Default |
+|:----|:-----|:--------|:--------|
+|`embedder`|`Embedder`| phidata provides many Embedders that abstract the interaction with embedding APIs and utilize it to generate embeddings. Check out other embedders [here](https://docs.phidata.com/embedder/introduction) | `OpenAIEmbedder` |
+|`distance`|`List[str]`| The choice of distance metric used to calculate the similarity between vectors, which directly impacts search results and performance in vector databases. |`Distance.cosine`|
+|`connection`|`lancedb.db.LanceTable`| LanceTable can be accessed through `.connection`. You can connect to an existing table of LanceDB, created outside of phidata, and utilize it. If not provided, it creates a new table using `table_name` parameter and adds it to `connection`. |`None`|
+|`uri`|`str`| It specifies the directory location of **LanceDB database** and establishes a connection that can be used to interact with the database. | `"/tmp/lancedb"` |
+|`table_name`|`str`|  If `connection` is not provided, it initializes and connects to a new **LanceDB table** with a specified(or default) name in the database present at `uri`. |`"phi"`|
+|`nprobes`|`int`| It refers to the number of partitions that the search algorithm examines to find the nearest neighbors of a given query vector. Higher values will yield better recall (more likely to find vectors if they exist) at the expense of latency. |`20`|
+
+
+!!! note
+    Since we just initialized the KnowledgeBase. The VectorDB table that corresponds to this Knowledge Base is not yet populated with our data. It will be populated in **Step 3**, once we perform the `load` operation. 
+    
+    You can check the state of the LanceDB table using - `knowledge_base.vector_db.connection.to_pandas()`
+
+Now that the Knowledge Base is initialized, , we can go to **step 2**.
+
+## **Step 2** -  Create an assistant with our choice of LLM and reference to the knowledge base.
+
+
+=== "openai_assistant.py"
+
+    ```python
+    # define an assistant with gpt-4o-mini llm and reference to the knowledge base created above
+    assistant = Assistant(
+        llm=OpenAIChat(model="gpt-4o-mini", max_tokens=1000, temperature=0.3,api_key = openai.api_key),
+        description="""You are an Expert in explaining youtube video transcripts. You are a bot that takes transcript of a video and answer the question based on it.

+        [timestamp] - highlight 2
+        ... so on
+        
+        Your task is to understand the user question, and provide an answer using the provided contexts. Your answers are correct, high-quality, and written by an domain expert. If the provided context does not contain the answer, simply state,'The provided context does not have the answer.'""",
+        knowledge_base=knowledge_base,
+        add_references_to_prompt=True,
+    )
+    ```
+
+=== "ollama_assistant.py"
+
+    ```python
+    # define an assistant with llama3.1 llm and reference to the knowledge base created above
+    assistant = Assistant(
+        llm=Ollama(model="llama3.1"),
+        description="""You are an Expert in explaining youtube video transcripts. You are a bot that takes transcript of a video and answer the question based on it.

+        knowledge_base=knowledge_base,
+        add_references_to_prompt=True,
+    )
+    ```
+
+Assistants add **memory**, **knowledge**, and **tools** to LLMs. Here we will add only **knowledge** in this example. 
+
+Whenever we will give a query to LLM, the assistant will retrieve relevant information from our **Knowledge Base**(table in LanceDB) and pass it to LLM along with the user query in a structured way. 
+
+- The `add_references_to_prompt=True` always adds information from the knowledge base to the prompt, regardless of whether it is relevant to the question.
+
+To know more about an creating assistant in phidata, check out [phidata docs](https://docs.phidata.com/assistants/introduction) here.
+
+## **Step 3** - Load data to Knowledge Base.
+
+```python
+# load out data into the knowledge_base (populating the LanceTable)
+assistant.knowledge_base.load(recreate=False)
+```
+The above code loads the data to the Knowledge Base(LanceDB Table) and now it is ready to be used by the assistant. 
+
+| Name| Type | Purpose | Default |
+|:----|:-----|:--------|:--------|
+|`recreate`|`bool`| If True, it drops the existing table and recreates the table in the vectorDB. |`False`|
+|`upsert`|`bool`| If True and the vectorDB supports upsert, it will upsert documents to the vector db. | `False` |
+|`skip_existing`|`bool`| If True, skips documents that already exist in the vectorDB when inserting. |`True`|
+
+??? tip "What is upsert?"
+    Upsert is a database operation that combines "update" and "insert". It updates existing records if a document with the same identifier does exist, or inserts new records if no matching record exists. This is useful for maintaining the most current information without manually checking for existence.
+
+During the Load operation, phidata directly interacts with the LanceDB library and performs the loading of the table with our data in the following steps -     
+
+1. **Creates** and **initializes** the table if it does not exist.
+
+2. Then it **splits** our data into smaller **chunks**.
+
+    ??? question "How do they create chunks?"
+        **phidata** provides many types of **Knowledge Bases** based on the type of data. Most of them :material-information-outline:{ title="except LlamaIndexKnowledgeBase and LangChainKnowledgeBase"} has a property method called `document_lists` of type `Iterator[List[Document]]`. During the load operation, this property method is invoked. It traverses on the data provided by us (in this case, a text file(s)) using `reader`. Then it **reads**, **creates chunks**, and **encapsulates** each chunk inside a `Document` object and yields **lists of `Document` objects** that contain our data.
+
+3. Then **embeddings** are created on these chunks are **inserted** into the LanceDB Table 
+
+    ??? question "How do they insert your data as different rows in LanceDB Table?"
+        The chunks of your data are in the form - **lists of `Document` objects**. It was yielded in the step above.
+
+        for each `Document` in `List[Document]`, it does the following operations:
+        
+        - Creates embedding on `Document`.
+        - Cleans the **content attribute**(chunks of our data is here) of `Document`.
+        - Prepares data by creating `id` and loading `payload` with the metadata related to this chunk. (1)
+            { .annotate }
+
+            1.  Three columns will be added to the table - `"id"`, `"vector"`, and `"payload"` (payload contains various metadata including **`content`**)
+                
+        - Then add this data to LanceTable. 
+
+4. Now the internal state of `knowledge_base` is changed (embeddings are created and loaded in the table ) and it **ready to be used by assistant**.
+
+## **Step 4** - Start a cli chatbot with access to the Knowledge base  
+
+```python
+# start cli chatbot with knowledge base
+assistant.print_response("Ask me about something from the knowledge base")
+while True:
+    message = Prompt.ask(f"[bold] :sunglasses: User [/bold]")
+    if message in ("exit", "bye"):
+        break
+    assistant.print_response(message, markdown=True)
+```

-## Basic recipe
+**FiftyOne** provides an API to create LanceDB tables and run similarity queries, both **programmatically in Python** and via **point-and-click in the App**.
 
-The basic workflow shown below uses LanceDB to create a similarity index on your FiftyOne
-datasets:
+Let's get started and see how to use **LanceDB** to create a **similarity index** on your FiftyOne datasets.
+
+## Overview 
+
+**[Embeddings](../embeddings/understanding_embeddings.md)** are foundational to all of the **vector search** features. In FiftyOne, embeddings are managed by the [**FiftyOne Brain**](https://docs.voxel51.com/user_guide/brain.html) that provides powerful machine learning techniques designed to transform how you curate your data from an art into a measurable science. 
+
+!!!question "Have you ever wanted to find the images most similar to an image in your dataset?"
+    The **FiftyOne Brain** makes computing **visual similarity** really easy. You can compute the similarity of samples in your dataset using an embedding model and store the results in the **brain key**. 
+
+    You can then sort your samples by similarity or use this information to find potential duplicate images.
+
+Here we will be doing the following : 
+
+1. **Create Index** - In order to run similarity queries against our media, we need to **index** the data. We can do this via the `compute_similarity()` function. 
+
+    -  In the function, specify the **model** you want to use to generate the embedding vectors, and what **vector search engine** you want to use on the **backend** (here LanceDB). 
+    
+    !!!tip
+        You can also give the similarity index a name(`brain_key`), which is useful if you want to run vector searches against multiple indexes.
+
+2. **Query** - Once you have generated your similarity index, you can query your dataset with `sort_by_similarity()`. The query can be any of the following:
+
+    - An ID (sample or patch)
+    - A query vector of same dimension as the index
+    - A list of IDs (samples or patches)
+    - A text prompt (search semantically)
+
+## Prerequisites: install necessary dependencies
+
+1. **Create and activate a virtual environment**
+
+    Install virtualenv package and run the following command in your project directory.
+    ```python
+    python -m venv fiftyone_

+
+2. **Install the following packages in the virtual environment**
+
+    To install FiftyOne, ensure you have activated any virtual environment that you are using, then run
+    ```python
+    pip install fiftyone

+
+    Performing a similarity search on a `DatasetView` will only return results from the view; if the view contains samples that were not included in the index, they will never be included in the result.

+Alternatively, you can **permanently** configure FiftyOne to use the LanceDB backend creating a `brain_config.json` at `~/.fiftyone/brain_config.json`. The JSON file may contain any desired subset of config fields that you wish to customize.
+
+```json
+{
+    "default_similarity_backend": "lancedb"
+}
+```
+This will override the default `brain_config` and will set it according to your customization. You can check the configuration by running the following code : 
+
+```python
+import fiftyone.brain as fob
+# Print your current brain config
+print(fob.brain_config)
+```
+
+## LanceDB config parameters
+
+The LanceDB backend supports query parameters that can be used to customize your similarity queries. These parameters include:
+
+| Name| Purpose | Default |
+|:----|:--------|:--------|
+|**table_name**|The name of the LanceDB table to use. If none is provided, a new table will be created|`None`|
+|**metric**|The embedding distance metric to use when creating a new table. The supported values are ("cosine", "euclidean")|`"cosine"`|
+|**uri**| The database URI to use. In this Database URI, tables will be created. |`"/tmp/lancedb"`|
+
+There are two ways to specify/customize the parameters:
+
+1. **Using `brain_config.json` file** 
+
+    ```json
+    {
+        "similarity_backends": {
+            "lancedb": {
+                "table_name": "your-table",
+                "metric": "euclidean",
+                "uri": "/tmp/lancedb"
+            }
+        }
+    }
+    ```
+
+2. **Directly passing to `compute_similarity()` to configure a specific new index** : 
+
+    ```python
+    lancedb_index = fob.compute_similarity(
+        ...
+        backend="lancedb",
+        brain_key="lancedb_index",
+        table_name="your-table",
+        metric="euclidean",
+        uri="/tmp/lancedb",
+    )
+    ```
+

+### mergeInsert
+
+▸ **mergeInsert**(`on`, `data`, `args`): `Promise`\<`void`\>
+
+Runs a "merge insert" operation on the table
+
+This operation can add rows, update rows, and remove rows all in a single
+transaction. It is a very generic tool that can be used to create
+behaviors like "insert if not exists", "update or insert (i.e. upsert)",
+or even replace a portion of existing data with new data (e.g. replace
+all data where month="january")
+
+The merge insert operation works by combining new data from a
+**source table** with existing data in a **target table** by using a
+join.  There are three categories of records.
+
+"Matched" records are records that exist in both the source table and
+the target table. "Not matched" records exist only in the source table
+(e.g. these are new data) "Not matched by source" records exist only
+in the target table (this is old data)
+
+The MergeInsertArgs can be used to customize what should happen for
+each category of data.
+
+Please note that the data may appear to be reordered as part of this
+operation.  This is because updated rows will be deleted from the
+dataset and then reinserted at the end with the new values.
+
+#### Parameters
+
+| Name | Type | Description |
+| :------ | :------ | :------ |
+| `on` | `string` | a column to join on. This is how records from the source table and target table are matched. |
+| `data` | `Table`\<`any`\> \| `Record`\<`string`, `unknown`\>[] | the new data to insert |
+| `args` | [`MergeInsertArgs`](../interfaces/MergeInsertArgs.md) | parameters controlling how the operation should behave |

+# Interface: ColumnAlteration
+
+A definition of a column alteration. The alteration changes the column at
+`path` to have the new name `name`, to be nullable if `nullable` is true,
+and to have the data type `data_type`. At least one of `rename` or `nullable`
+must be provided.

+The path to the column to alter. This is a dot-separated path to the column.
+If it is a top-level column then it is just the name of the column. If it is
+a nested column then it is the path to the column, e.g. "a.b.c" for a column
+`c` nested inside a column `b` nested inside a column `a`.

+filter where fields with the prefix "target." refer to fields

+example, the filter "target.lastUpdated < source.lastUpdated" will
+only update matched rows when the incoming `lastUpdated` value is
+newer.
+
+Rows that do not match the filter will not be updated.  Rows that
+do not match the filter do become "not matched" rows.

+
+• **mergeInsert**: (`on`: `string`, `data`: `Table`\<`any`\> \| `Record`\<`string`, `unknown`\>[], `args`: [`MergeInsertArgs`](MergeInsertArgs.md)) => `Promise`\<`void`\>
+
+#### Type declaration
+
+▸ (`on`, `data`, `args`): `Promise`\<`void`\>
+
+Runs a "merge insert" operation on the table
+
+This operation can add rows, update rows, and remove rows all in a single
+transaction. It is a very generic tool that can be used to create
+behaviors like "insert if not exists", "update or insert (i.e. upsert)",
+or even replace a portion of existing data with new data (e.g. replace
+all data where month="january")
+
+The merge insert operation works by combining new data from a
+**source table** with existing data in a **target table** by using a
+join.  There are three categories of records.
+
+"Matched" records are records that exist in both the source table and
+the target table. "Not matched" records exist only in the source table
+(e.g. these are new data) "Not matched by source" records exist only
+in the target table (this is old data)
+
+The MergeInsertArgs can be used to customize what should happen for
+each category of data.
+
+Please note that the data may appear to be reordered as part of this
+operation.  This is because updated rows will be deleted from the
+dataset and then reinserted at the end with the new values.
+
+##### Parameters

+### makeArrowTable
+
+▸ **makeArrowTable**(`data`, `options?`): `ArrowTable`
+
+An enhanced version of the makeTable function from Apache Arrow
+that supports nested fields and embeddings columns.
+
+This function converts an array of Record<String, any> (row-major JS objects)
+to an Arrow Table (a columnar structure)
+
+Note that it currently does not support nulls.
+
+If a schema is provided then it will be used to determine the resulting array
+types.  Fields will also be reordered to fit the order defined by the schema.
+
+If a schema is not provided then the types will be inferred and the field order
+will be controlled by the order of properties in the first record.
+
+If the input is empty then a schema must be provided to create an empty table.
+
+When a schema is not specified then data types will be inferred.  The inference
+rules are as follows:
+
+ - boolean => Bool
+ - number => Float64
+ - String => Utf8
+ - Buffer => Binary
+ - Record<String, any> => Struct
+ - Array<any> => List
+
+#### Parameters
+
+| Name | Type | Description |
+| :------ | :------ | :------ |
+| `data` | `Record`\<`string`, `any`\>[] | input data |
+| `options?` | `Partial`\<[`MakeArrowTableOptions`](classes/MakeArrowTableOptions.md)\> | options to control the makeArrowTable call. |
+
+#### Returns
+
+`ArrowTable`
+
+**`Example`**
+
+```ts
+
+import { fromTableToBuffer, makeArrowTable } from "../arrow";
+import { Field, FixedSizeList, Float16, Float32, Int32, Schema } from "apache-arrow";
+
+const schema = new Schema([
+  new Field("a", new Int32()),
+  new Field("b", new Float32()),
+  new Field("c", new FixedSizeList(3, new Field("item", new Float16()))),
+ ]);
+ const table = makeArrowTable([
+   { a: 1, b: 2, c: [1, 2, 3] },
+   { a: 4, b: 5, c: [4, 5, 6] },
+   { a: 7, b: 8, c: [7, 8, 9] },
+ ], { schema });
+```
+
+By default it assumes that the column named `vector` is a vector column
+and it will be converted into a fixed size list array of type float32.
+The `vectorColumns` option can be used to support other vector column
+names and data types.
+
+```ts
+
+const schema = new Schema([
+   new Field("a", new Float64()),
+   new Field("b", new Float64()),
+   new Field(
+     "vector",
+     new FixedSizeList(3, new Field("item", new Float32()))
+   ),
+ ]);
+ const table = makeArrowTable([
+   { a: 1, b: 2, vector: [1, 2, 3] },
+   { a: 4, b: 5, vector: [4, 5, 6] },
+   { a: 7, b: 8, vector: [7, 8, 9] },
+ ]);
+ assert.deepEqual(table.schema, schema);
+```
+
+You can specify the vector column types and names using the options as well
+
+```typescript
+
+const schema = new Schema([
+   new Field('a', new Float64()),
+   new Field('b', new Float64()),
+   new Field('vec1', new FixedSizeList(3, new Field('item', new Float16()))),
+   new Field('vec2', new FixedSizeList(3, new Field('item', new Float16())))
+ ]);
+const table = makeArrowTable([
+   { a: 1, b: 2, vec1: [1, 2, 3], vec2: [2, 4, 6] },
+   { a: 4, b: 5, vec1: [4, 5, 6], vec2: [8, 10, 12] },
+   { a: 7, b: 8, vec1: [7, 8, 9], vec2: [14, 16, 18] }
+ ], {
+   vectorColumns: {
+     vec1: { type: new Float16() },

+====================================================================
+Salesforce AI Research introduces SFR-RAG, a 9-billion-parameter language model trained with a significant emphasis on reliable, precise, and faithful contextual generation abilities specific to real-world RAG use cases and relevant agentic tasks. They include precise factual knowledge extraction, distinguishing relevant against distracting contexts, citing appropriate sources along with answers, producing complex and multi-hop reasoning over multiple contexts, consistent format following, as well as refraining from hallucination over unanswerable queries.

+
+To reliably evaluate LLMs in contextual question-answering for RAG, Saleforce introduced [ContextualBench](https://huggingface.co/datasets/Salesforce/ContextualBench?ref=blog.salesforceairesearch.com), featuring 7 benchmarks like [HotpotQA](https://arxiv.org/abs/1809.09600?ref=blog.salesforceairesearch.com) and [2WikiHopQA](https://www.aclweb.org/anthology/2020.coling-main.580/?ref=blog.salesforceairesearch.com) with consistent setups. 
+
+SFR-RAG outperforms GPT-4o, achieving state-of-the-art results in 3 out of 7 benchmarks, and significantly surpasses Command-R+ while using 10 times fewer parameters. It also excels at handling context, even when facts are altered or conflicting.

+Accepted Arguments
+----------------
+| Argument | Type | Default | Description |
+| --- | --- | --- | --- |
+| `model_name` | `str` | `None` | The name of the reranker model to use. Available models are: rerank-2, rerank-2-lite |
+| `column` | `str` | `"text"` | The name of the column to use as input to the cross encoder model. |
+| `top_n` | `str` | `None` | The number of results to return. If None, will return all results. |

 option that performs the filter prior to vector search. This can be useful to narrow down on
 the search space on a very large dataset to reduce query latency.
 
+Note that both pre-filtering and post-filtering can yield false positives. For pre-filtering, if the filter is too selective, it might eliminate relevant items that the vector search would have otherwise identified as a good match. In this case, increasing `nprobes` parameter will help reduce such false positives. It is recommended to set `use_index=false` if you know that the filter is highly selective.
+
+Similarly, a highly selective post-filter can lead to false positives. Increasing both `nprobes` and `refine_factor` can mitigate this issue. When deciding between pre-filtering and post-filtering, pre-filtering is generally the safer choice if you're uncertain.

+## Getting help
+
+The following sections provide various diagnostics and troubleshooting tips for LanceDB.
+These can help you provide additional information when asking questions or making
+error reports.
+
+For trouble shooting, the best place to ask is in our Discord, under the relevant
+language channel. By asking in the language-specific channel, it makes it more
+likely that someone who knows the answer will see your question.
+
+## Enabling logging
+
+To provide more information, especially for LanceDB Cloud related issues, enable
+debug logging. You can set the `LANCEDB_LOG` environment variable:
+
+```shell
+export LANCEDB_LOG=debug
+```
+
+You can turn off colors and formatting in the logs by setting
+
+```shell
+export LANCEDB_LOG_STYLE=never
+```
+
+## Explaining query plans
+
+If you have slow queries or unexpected query results, it can be helpful to
+print the resolved query plan. You can use the `explain_plan` method to do this:
+
+* Python Sync: [LanceQueryBuilder.explain_plan][lancedb.query.LanceQueryBuilder.explain_plan]
+* Python Async: [AsyncQueryBase.explain_plan][lancedb.query.AsyncQueryBase.explain_plan]
+* Node @lancedb/lancedb: [LanceQueryBuilder.explainPlan](/lancedb/js/classes/QueryBase/#explainplan)
