Class MultiMatchQuery

java.lang.Object

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

de.julielab.elastic.query.components.data.query.MultiMatchQuery

public class MultiMatchQuery
extends SearchServerQuery

For this query, the query string itself and the fields, on which to perform the query, are separated (in contrast to LuceneSyntaxQuery). The query string will be analyzed for each field separately before matching. The resulting tokens will result in a boolean query, connected by the operator given by the operator field which defaults to or. The query string is not parsed in any way for boolean operators, field names, boosts etc.
