Class ExpressionQueryList

java.lang.Object

org.elasticsearch.xpack.esql.enrich.ExpressionQueryList

All Implemented Interfaces:

LookupEnrichQueryGenerator

public class ExpressionQueryList
extends Object
implements LookupEnrichQueryGenerator

A LookupEnrichQueryGenerator that combines multiple conditions into a single query list. Each query in the resulting query will be a conjunction of all queries from the input lists at the same position. In addition, we support an optional pre-join filter that will be applied to all queries if it is pushable. If the pre-join filter cannot be pushed down to Lucene, it will be ignored.
