open class SeededKnnVectorQuery : AbstractKnnVectorQuery

This is a version of knn vector query that provides a query seed to initiate the vector search. NOTE: The underlying format is free to ignore the provided seed

Functions

createWeight

open fun createWeight(searcher: IndexSearcher, scoreMode: ScoreMode, boost: Float): Weight

Expert: Constructs an appropriate Weight implementation for this query.

equals

open operator override fun equals(o: Any?): Boolean

Override and implement query instance equivalence properly in a subclass. This is required so that QueryCache works properly.

hashCode

open override fun hashCode(): Int

Override and implement query hash code properly in a subclass. This is required so that [ ] works properly.

rewrite

open override fun rewrite(indexSearcher: IndexSearcher): Query

Expert: called to re-write queries into primitive queries. For example, a PrefixQuery will be rewritten into a BooleanQuery that consists of TermQuerys.

toString

open override fun toString(): String

Prints a query to a string.

open override fun toString(field: String?): String

Prints a query to a string, with field assumed to be the default field and omitted.

visit

open override fun visit(visitor: QueryVisitor)

Recurse through the query tree, visiting any child queries.
