=== Bool Query
|
||
|
|
|
||
|
|
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:
|
||
|
|
|
||
|
|
[cols="<,<",options="header",]
|
||
|
|
|=======================================================================
|
||
|
|
|Occur |Description
|
||
|
|
|`must` |The clause (query) must appear in matching documents.
|
||
|
|
|
||
|
|
|`should` |The clause (query) should appear in the matching document. In
|
||
|
|
a boolean query with no `must` clauses, one or more `should` clauses
|
||
|
|
must match a document. The minimum number of should clauses to match can
|
||
|
|
be set using the
|
||
|
|
<<query-dsl-minimum-should-match,`minimum_should_match`>>
|
||
|
|
parameter.
|
||
|
|
|
||
|
|
|`must_not` |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.
