347515aa51 fix: support list of numpy f16 floats as query vector (#1931)
User reported on Discord, when using
`table.vector_search([np.float16(1.0), np.float16(2.0), ...])`, it
yields `TypeError: 'numpy.float16' object is not iterable`

db125013fc docs: better formatting for Node API docs (#1892)
* Sets `"useCodeBlocks": true`
* Adds a post-processing script `nodejs/typedoc_post_process.js` that
puts the parameter description on the same line as the parameter name,
like it is in our Python docs. This makes the text hierarchy clearer in
those sections and also makes the sections shorter.

Most of the time, setting nprobes to cover 5-15% of the dataset should achieve high recall with low latency.<br/>

`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

## Methods
### bitmap()

static bitmap(): Index
```
Create a bitmap index.
A `Bitmap` index stores a bitmap for each distinct value in the column for every row.
This index works best for low-cardinality columns, where the number of unique values
is small (i.e., less than a few hundreds).

### fts()
```ts
static fts(options?): Index

Create a full text search index
A full text search index is an index on a string column, so that you can conduct full
text searches on the column.
The results of a full text search are ordered by relevance measured by BM25.
You can combine filters with full text search.
For now, the full text search index only supports English, and doesn't support phrase search.
#### Parameters
* **options?**: `Partial`&lt;`FtsOptions`&gt;

HNSW-PQ stands for Hierarchical Navigable Small World - Product Quantization.
It is a variant of the HNSW algorithm that uses product quantization to compress
the vectors.

### labelList()
Create a full text search index
```ts
static labelList(): Index
```
This index is used to search for text data. The index is created by tokenizing the text
into words and then storing occurrences of these words in a data structure called inverted index
that allows for fast search.
Create a label list index.
During a search the query is tokenized and the inverted index is used to find the rows that
contain the query words. The rows are then scored based on BM25 and the top scoring rows are
sorted and returned.
#### Parameters
**options?**: `Partial`&lt;[`FtsOptions`](../interfaces/FtsOptions.md)&gt;
LabelList index is a scalar 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.

In addition doing text search on the LanceDB Table, also
find the nearest vectors to the given query vector.
This converts the query from a FTS Query to a Hybrid query. Results
from the vector search will be combined with results from the FTS query.
This method will attempt to convert the input to the query vector
expected by the embedding model. If the input cannot be converted
then an error will be thrown.
By default, there is no embedding model, and the input should be
something that can be converted to a pyarrow array of floats. This
includes lists, numpy arrays, and tuples.
If there is only one vector column (a column whose data type is a
fixed size list of floats) then the column does not need to be specified.
If there is more than one vector column you must use
[AsyncVectorQuery.column][lancedb.query.AsyncVectorQuery.column] to specify
which column you would like to compare with.
If no index has been created on the vector column then a vector query
will perform a distance comparison between the query vector and every
vector in the database and then sort the results. This is sometimes
called a "flat search"
For small databases, with tens of thousands of vectors or less, this can
be reasonably fast. In larger databases you should create a vector index
on the column. If there is a vector index then an "approximate" nearest
neighbor search (frequently called an ANN search) will be performed. This
search is much faster, but the results will be approximate.
The query can be further parameterized using the returned builder. There
are various ANN search parameters that will let you fine tune your recall
accuracy vs search latency.
Hybrid searches always have a [limit][]. If `limit` has not been called then
a default `limit` of 10 will be used.
Typically, a single vector is passed in as the query. However, you can also
pass in multiple vectors. This can be useful if you want to find the nearest
vectors to multiple query vectors. This is not expected to be faster than
making multiple queries concurrently; it is just a convenience method.
If multiple vectors are passed in then an additional column `query_index`
will be added to the results. This column will contain the index of the
query vector that the result is nearest to.
