# Class: AutoQuery
|
||||
|
||||
A builder for automatic string searches.
|
||||
|
||||
Automatic search determines whether to use full-text or vector search from
|
||||
the table revision selected for each execution. This builder exposes the
|
||||
common operations supported by both query families.

||||

## Methods

||||
### analyzePlan()
|
||||
|
||||
```ts
|
||||
analyzePlan(distributedMetrics?): Promise<string>
|
||||
```
|
||||
|
||||
Executes the query and returns the physical query plan annotated with runtime metrics.
|
||||
|
||||
This is useful for debugging and performance analysis, as it shows how the query was executed
|
||||
and includes metrics such as elapsed time, rows processed, and I/O statistics.
|
||||
|
||||
#### Parameters
|
||||
|
||||
* **distributedMetrics?**: [`AnalyzePlanDistributedMetrics`](../type-aliases/AnalyzePlanDistributedMetrics.md)
|
||||
How distributed worker metrics are displayed for remote query plans.
|
||||
Defaults to `"aggregate"`.
|
||||
|
||||
#### Returns
|
||||
|
||||
`Promise`<`string`>
|
||||
|
||||
A query execution plan with runtime metrics for each step.
|
||||
|
||||
#### Example
|
||||
|
||||
```ts
|
||||
import * as lancedb from "@lancedb/lancedb"
|
||||
|
||||
const db = await lancedb.connect("./.lancedb");
|
||||
const table = await db.createTable("my_table", [
|
||||
{ vector: [1.1, 0.9], id: "1" },
|
||||
]);
|
||||
|
||||
const plan = await table.query().nearestTo([0.5, 0.2]).analyzePlan();
|
||||
|
||||

### execute()
|
||||
|
||||
```ts
|

protected execute(options?): AsyncGenerator<RecordBatch<any>, void, unknown>
|

```
|

#### Parameters
|
||||
|
||||
* **options?**: `Partial`<[`QueryExecutionOptions`](../interfaces/QueryExecutionOptions.md)>
|

#### Returns

|
||||
|
||||
By default, LanceDb will use many threads to calculate results and, when
|
||||
the result set is large, multiple batches will be processed at one time.
|
||||
This readahead is limited however and backpressure will be applied if this
|
||||
stream is consumed slowly (this constrains the maximum memory used by a
|
||||
single query)

#### Parameters
|

Skip searching un-indexed data. This can make search faster, but will miss

|
||||
returned by the query before executing it.

### select()
|
||||
|
||||
```ts
|
||||
select(columns): this
|
||||
```
|
||||
|
||||
Return only the specified columns.
|
||||
|
||||
By default a query will return all columns from the table. However, this can have
|
||||
a very significant impact on latency. LanceDb stores data in a columnar fashion. This
|
||||
means we can finely tune our I/O to select exactly the columns we need.
|
||||
|
||||
As a best practice you should always limit queries to the columns that you need. If you
|
||||
pass in an array of column names then only those columns will be returned.
|
||||
|
||||
You can also use this method to create new "dynamic" columns based on your existing columns.
|
||||
For example, you may not care about "a" or "b" but instead simply want "a + b". This is often
|
||||
seen in the SELECT clause of an SQL query (e.g. `SELECT a+b FROM my_table`).
|
||||
|
||||
To create dynamic columns you can pass in a Map<string, string>. A column will be returned
|
||||
for each entry in the map. The key provides the name of the column. The value is
|
||||
an SQL string used to specify how the column is calculated.
|
||||
|
||||
For example, an SQL query might state `SELECT a + b AS combined, c`. The equivalent
|
||||
input to this method would be:
|
||||
|
||||
#### Parameters
|
||||
|
||||
* **columns**: `string` \| `string`[] \| `Record`<`string`, `string`> \| `Map`<`string`, `string`>
|
||||
|
||||
#### Returns
|
||||
|
||||
`this`
|
||||
|
||||
#### Example
|
||||
|
||||
```ts
|
||||
new Map([["combined", "a + b"], ["c", "c"]])
|
||||
|
||||
Columns will always be returned in the order given, even if that order is different than
|
||||
the order used when adding the data.
|
||||
|
||||
Note that you can pass in a `Record<string, string>` (e.g. an object literal). This method
|
||||
uses `Object.entries` which should preserve the insertion order of the object. However,
|
||||
object insertion order is easy to get wrong and `Map` is more foolproof.

### useLsm()
|
||||
|
||||
```ts
|
||||
useLsm(enable): this
|
||||
```
|
||||
|
||||
Control MemWAL read routing for this query.
|
||||
|
||||
By default (unset), when the table carries a MemWAL write spec (see
|
||||
[Table#setLsmWriteSpec](Table.md#setlsmwritespec)), reads are routed through the LSM scanner so
|
||||
they also return data written via the `mergeInsert` LSM path that has not yet
|
||||
been compacted into the base table (the active/frozen in-memory memtables and
|
||||
the flushed generations), deduplicated by primary key; a table without a spec
|
||||
reads the base table.
|
||||
|
||||
#### Parameters
|
||||
|
||||
* **enable**: `boolean`
|
||||
`true` forces the LSM scanner and errors if the table has no
|
||||
MemWAL write spec. `false` bypasses the MemWAL and reads the base table only,
|
||||
even when a spec is present.
|
||||
Note: the LSM scanner does not support every query shape (e.g. reranking,
|
||||
hybrid search, `orderBy`). On a MemWAL table those shapes error unless
|
||||
`useLsm(false)` is set, because a base-only read would silently exclude
|
||||
un-compacted MemWAL data.

||||

#### Returns

### where()
|
||||
|
||||
```ts
|
||||
where(predicate): this
|
||||
```
|
||||
|
||||
A filter statement to be applied to this query.
|
||||
|
||||
The filter should be supplied as an SQL query string. For example:
|
||||
|
||||
#### Parameters
|
||||
|
||||
* **predicate**: `string`
|
||||
|
||||
#### Returns
|
||||
|
||||
`this`
|
||||
|
||||
#### Example
|
||||
|
||||
```ts
|
||||
x > 10
|
||||
y > 0 AND y < 100
|
||||
x > 5 OR y = 'test'
|
||||
|
||||
Filtering performance can often be improved by creating a scalar index
|
||||
on the filter column(s).
|
||||
|
||||
Calling this multiple times combines the filters with a logical AND rather
|
||||
than replacing the previous filter.

function getRegistry(): EmbeddingFunctionRegistry
|

```
|
||||
|
||||
Utility function to get the global instance of the registry
|
||||
Get the global embedding function registry.
|
||||
|
||||
LanceDB built-in providers are initialized when this public API is first
|
||||
used, so importing the root package does not change automatic search
|
||||
selection for tables without embedding metadata.
|
||||
|
||||
## Returns
|
||||
|
||||
[`EmbeddingFunctionRegistry`](../classes/EmbeddingFunctionRegistry.md)
|
||||
|
||||
`EmbeddingFunctionRegistry` The global instance of the registry
|
||||
|
||||
## Example
|
||||
|
||||
```ts
|
||||
const registry = getRegistry();
|
||||
const openai = registry.get("openai").create();
