Class BoolQuery

java.lang.Object

de.julielab.elastic.query.components.data.query.SearchServerQuery

de.julielab.elastic.query.components.data.query.BoolQuery

public class BoolQuery
extends SearchServerQuery

This query type is equivalent to Lucene's BooleanQuery. It wraps around other queries and with that, forms clauses with the operators must should and must_not. For a document to match, it has to match all must clauses, gets better score for should clauses and is rejected for matching must_not clauses. A clause may contain multiple nested queries. In this case, the three operators roughly translate into boolean and, or and not operators, respectively.
