+## Filtering
+
+Currently the LanceDB full text search feature supports *post-filtering*, meaning filters are
+applied on top of the full text search results. This can be invoked via the familiar
+`where` syntax:
+
+```python
+table.search("puppy").limit(10).where("meta='foo'").to_list()
+```
+
+## Syntax
+
+For full-text search you can perform either a phrase query like "the old man and the sea", 
+or a structured search query like "(Old AND Man) AND Sea".
+Double quotes are used to disambiguate.
+
+For example: 
+
+If you intended "they could have been dogs OR cats" as a phrase query, this actually
+raises a syntax error since `OR` is a recognized operator. If you make `or` lower case,
+this avoids the syntax error. However, it is cumbersome to have to remember what will
+conflict with the query syntax. Instead, if you search using 
+`table.search('"they could have been dogs OR cats"')`, then the syntax checker avoids
+checking inside the quotes.
+
+
+## Configurations
+
+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.
+
+```python
+# configure a 512MB heap size
+heap = 1024 * 1024 * 512

+A Table is a collection of Records in a LanceDB Database. Tables in Lance have a schema that defines the columns and their types. These schemas can include nested columns and can evolve over time.

     table = db.create_table(table_name, schema=Content)
     ```
 
+    #### Nested schemas
+
+    Sometimes your data model may contain nested objects.
+    For example, you may want to store the document string
+    and the document soure name as a nested Document object:
+
+    ```python
+    class Document(BaseModel):
+        content: str
+        source: str
+    ```
+
+    This can be used as the type of a LanceDB table column:
+
+    ```python
+    class NestedSchema(LanceModel):
+        id: str
+        vector: Vector(1536)
+        document: Document
+
+    tbl = db.create_table("nested_table", schema=NestedSchema, mode="overwrite")
+    ```
+
+    This creates a struct column called "document" that has two subfields 
+    called "content" and "source":
+
+    ```
+    In [28]: tbl.schema
+    Out[28]:
+    id: string not null
+    vector: fixed_size_list<item: float>[1536] not null
+        child 0, item: float
+    document: struct<content: string not null, source: string not null> not null
+        child 0, content: string not null
+        child 1, source: string not null    
+    ```
+
+    #### Validators
+
+    Note that neither pydantic nor pyarrow automatically validates that input data
+    is of the *correct* timezone, but this is easy to add as a custom field validator:
+
+    ```python
+    from datetime import datetime
+    from zoneinfo import ZoneInfo
+
+    from lancedb.pydantic import LanceModel
+    from pydantic import Field, field_validator, ValidationError, ValidationInfo
+
+    tzname = "America/New_York"
+    tz = ZoneInfo(tzname)
+
+    class TestModel(LanceModel):
+        dt_with_tz: datetime = Field(json_schema_extra={"tz": tzname})
+
+        @field_validator('dt_with_tz')
+        @classmethod
+        def tz_must_match(cls, dt: datetime) -> datetime:
+            assert dt.tzinfo == tz
+            return dt        
+
+    ok = TestModel(dt_with_tz=datetime.now(tz))
+
+    try:
+        TestModel(dt_with_tz=datetime.now(ZoneInfo("Asia/Shanghai")))
+        assert 0 == 1, "this should raise ValidationError"
+    except ValidationError:
+        print("A ValidationError was raised.")
+        pass
+    ```
+
+    When you run this code it should print "A ValidationError was raised."
+
+    #### Pydantic custom types
+
+    LanceDB does NOT yet support converting pydantic custom types. If this is something you need,
+    please file a feature request on the [LanceDB Github repo](https://github.com/lancedb/lancedb/issues/new).

This means that failed transactions can leave around data that takes up disk space for up to 7 days. You can override this safety mechanism by setting this option to `true`, only if you promise there are no in progress writes while you run this operation.

+   *
+   * @param column The column to index
+   * @param replace If false, fail if an index already exists on the column
+   *
+   * Scalar indices, like vector indices, can be used to speed up scans.  A scalar
+   * index can speed up scans that contain filter expressions on the indexed column.
+   * For example, the following scan will be faster if the column `my_col` has
+   * a scalar index:
+   *
+   * ```ts
+   * const con = await lancedb.connect('./.lancedb');
+   * const table = await con.openTable('images');
+   * const results = await table.where('my_col = 7').execute();
+   * ```
+   *
+   * Scalar indices can also speed up scans containing a vector search and a
+   * prefilter:
+   *
+   * ```ts
+   * const con = await lancedb.connect('././lancedb');
+   * const table = await con.openTable('images');
+   * const results = await table.search([1.0, 2.0]).where('my_col != 7').prefilter(true);
+   * ```
+   *
+   * Scalar indices can only speed up scans for basic filters using
+   * equality, comparison, range (e.g. `my_col BETWEEN 0 AND 100`), and set
+   * membership (e.g. `my_col IN (0, 1, 2)`)
+   *
+   * Scalar indices can be used if the filter contains multiple indexed columns and
+   * the filter criteria are AND'd or OR'd together
+   * (e.g. `my_col < 0 AND other_col> 100`)
+   *
+   * Scalar indices may be used if the filter contains non-indexed columns but,
+   * depending on the structure of the filter, they may not be usable.  For example,
+   * if the column `not_indexed` does not have a scalar index then the filter
+   * `my_col = 0 OR not_indexed = 1` will not be able to use any scalar index on
+   * `my_col`.
+   *
+   * @examples
+   *

+
+        Scalar indices, like vector indices, can be used to speed up scans.  A scalar
+        index can speed up scans that contain filter expressions on the indexed column.
+        For example, the following scan will be faster if the column ``my_col`` has
+        a scalar index:
+
+        .. code-block:: python
+
+            import lancedb
+
+            db = lancedb.connect("/data/lance")
+            img_table = db.open_table("images")
+            my_df = img_table.search().where("my_col = 7", prefilter=True).to_pandas()
+
+        Scalar indices can also speed up scans containing a vector search and a
+        prefilter:
+
+        .. code-block::python
+
+            import lancedb
+
+            db = lancedb.connect("/data/lance")
+            img_table = db.open_table("images")
+            img_table.search([1, 2, 3, 4], vector_column_name="vector")
+                .where("my_col != 7", prefilter=True)
+                .to_pandas()
+
+        Scalar indices can only speed up scans for basic filters using
+        equality, comparison, range (e.g. ``my_col BETWEEN 0 AND 100``), and set
+        membership (e.g. `my_col IN (0, 1, 2)`)
+
+        Scalar indices can be used if the filter contains multiple indexed columns and
+        the filter criteria are AND'd or OR'd together
+        (e.g. ``my_col < 0 AND other_col> 100``)
+
+        Scalar indices may be used if the filter contains non-indexed columns but,
+        depending on the structure of the filter, they may not be usable.  For example,
+        if the column ``not_indexed`` does not have a scalar index then the filter
+        ``my_col = 0 OR not_indexed = 1`` will not be able to use any scalar index on
+        ``my_col``.
