# Class: BoostQuery
|
||||
|
||||
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.
|
||||
|
||||
## Implements
|
||||
|
||||
- [`FullTextQuery`](../interfaces/FullTextQuery.md)
|
||||
|
||||
## Constructors
|
||||
|
||||
### new BoostQuery()
|
||||
|
||||
```ts
|
||||
new BoostQuery(
|
||||
positive,
|
||||
negative,
|
||||
options?): BoostQuery
|
||||
```
|
||||
|
||||
Creates an instance of BoostQuery.
|
||||
The boost returns documents that match the positive query,
|
||||
but penalizes those that match the negative query.
|
||||
the penalty is controlled by the `negativeBoost` parameter.
|
||||
|
||||
#### Parameters
|
||||
|
||||
* **positive**: [`FullTextQuery`](../interfaces/FullTextQuery.md)
|
||||
The positive query that boosts the relevance score.
|
||||
|
||||
* **negative**: [`FullTextQuery`](../interfaces/FullTextQuery.md)
|
||||
The negative query that reduces the relevance score.
|
||||
|
||||
* **options?**
|
||||
Optional parameters for the boost query.
|
||||
- `negativeBoost`: The boost factor for the negative query (default is 0.0).
|
||||
|
||||
* **options.negativeBoost?**: `number`

# Enumeration: FullTextQueryType
|
||||
|
||||
Enum representing the types of full-text queries supported.
|
||||
|
||||
- `Match`: Performs a full-text search for terms in the query string.
|
||||
- `MatchPhrase`: Searches for an exact phrase match in the text.
|
||||
- `Boost`: Boosts the relevance score of specific terms in the query.
|
||||
- `MultiMatch`: Searches across multiple fields for the query terms.
