Merge branch 'main' into brendan/docs-availability
Resolve the docs Rust example lockfile: keep lance-namespace 8.0.0 and the remote client's windows-result 0.4.1 and windows-strings 0.5.1, which main's dependency update dropped, and take main's other updated versions.

Increasing this value will increase the recall of your query but will
|

also increase the latency of your query. The default value is 20. This

default is good for many cases but the best value to use will depend on
|

your data and the recall that you need to achieve.
|
||||
also increase the latency of your query. If this method is not called,
|
||||
Lance's adaptive probe defaults are used.
|
||||
|
||||
For best results we recommend tuning this parameter with a benchmark against
|
||||
your actual data to find the smallest possible value that will still give
|
||||
you the desired recall.
|
||||
|
||||
For more fine grained control over behavior when you have a very narrow filter
|
||||
you can use `minimumNprobes` and `maximumNprobes`. This method sets both
|
||||
the minimum and maximum to the same value.
|
||||
The value is retained as `nprobes` through client and server request
|
||||
construction. Lance sets both probe bounds to this value. Explicit minimum
|

or maximum settings can override their respective bounds.

### searchEffort()
|
||||
|
||||
```ts
|
||||
searchEffort(searchEffort): VectorQuery
|
||||
```
|
||||
|
||||
Set the initial IVF search effort to a finite value in [0, 1].
|
||||
|
||||
The default, null, uses Auto (internally 0.5). Zero starts at the caller
|
||||
minimum; one searches all partitions within the caller maximum. Later
|
||||
probing may continue when too few candidates are found.
|
||||
Any explicit effort, including 0.5, overrides nprobes in either call order.
|
||||
Explicit minimum and maximum bounds still apply. This is not a recall
|
||||
guarantee and does not change refinement or HNSW ef. The MemWAL LSM
|
||||
scanner does not yet support this option.

| `limit` | Number of results to return (the `k` in `k-ANN`). |
|
||||
| `nprobes` | Shorthand that sets both `minimum_nprobes` and `maximum_nprobes` to the same value. LanceDB defaults this to 20 which is a good default for many cases. At very high scales you will likely need to experiment to find your preferred recall / latency balance. |
|
||||
| `minimum_nprobes` | Minimum number of partitions scanned. |
|
||||
| `maximum_nprobes` | Maximum number of partitions scanned. Only scans more than `minimum_nprobes` if an initial pass does not return enough results — useful for narrow filters. Set to `0` to remove the cap. |
|
||||
| `nprobes` | Sets both `minimum_nprobes` and `maximum_nprobes` to the same value in Lance. Leave unset to use Lance's adaptive defaults. At very high scales you will likely need to experiment to find your preferred recall / latency balance. |
|
||||
| `minimum_nprobes` | Minimum number of partitions scanned. Leave unset to use Lance's default. |
|

| `maximum_nprobes` | Maximum number of partitions scanned. Only scans more than `minimum_nprobes` if an initial pass does not return enough results — useful for narrow filters. Leave unset, or set to `0`, to remove the cap. |
|
||||
| `ef` | HNSW search-time exploration factor. Start around `1.5 * k` and increase up to `10 * k` for higher recall. |
|
||||
| `refine_factor` | Reads and reranks additional candidates in memory to recover recall lost to quantization. Start between `5` and `50` (a factor of `25` reads and reranks the top `25 * k` candidates) and measure the latency cost, typically a few milliseconds, against the recall gained. |
|
||||
| `distance_range(lower_bound, upper_bound)` | Return only rows whose distance falls within `[lower_bound, upper_bound)`. Either bound is optional. Useful for near-duplicate detection or "close-enough" matching. |
