Bool Queryedit
A query that matches documents matching boolean combinations of other
queries. The bool query maps to Lucene BooleanQuery. It is built using
one or more boolean clauses, each clause with a typed occurrence. The
occurrence types are:
| Occur | Description |
|---|---|
| The clause (query) must appear in matching documents. |
| The clause (query) should appear in the matching document. In
a boolean query with no |
| The clause (query) must not appear in the matching documents. |
The bool query also supports disable_coord parameter (defaults to
false). Basically the coord similarity computes a score factor based
on the fraction of all query terms that a document contains. See Lucene
BooleanQuery for more details.
The bool query takes a more-matches-is-better approach, so the score from
each matching must or should clause will be added together to provide the
final _score for each document.
