feat: support a bunch or FTS features in JS SDK (#2431)
- operator for match query - slop for phrase query - boolean query <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **New Features** - Introduced support for boolean full-text search queries with AND/OR logic and occurrence conditions. - Added operator options for match and multi-match queries to control term combination logic. - Enabled phrase queries to specify proximity (slop) for flexible phrase matching. - Added new enumerations (`Operator`, `Occur`) and the `BooleanQuery` class for enhanced query expressiveness. - **Bug Fixes** - Improved validation and error handling for invalid operator and occurrence inputs in full-text queries. - **Tests** - Expanded test coverage with new cases for boolean queries and operator-based full-text searches. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Signed-off-by: BubbleCal <bubble-cal@outlook.com>

# Class: BooleanQuery
|
||||
|
||||
Represents a full-text query interface.
|
||||
This interface defines the structure and behavior for full-text queries,
|
||||
including methods to retrieve the query type and convert the query to a dictionary format.
|
||||

||||

new BooleanQuery(queries): BooleanQuery
|

```
|
||||
|
||||
Creates an instance of BooleanQuery.
|

|
||||
#### Parameters
|
||||
|
||||
* **queries**: [[`Occur`](../enumerations/Occur.md), [`FullTextQuery`](../interfaces/FullTextQuery.md)][]
|
||||
An array of (Occur, FullTextQuery objects) to combine.
|
||||
Occur specifies whether the query must match, or should match.
