* A query that matches documents matching boolean combinations of other queries. |

* |
|
8
|
|
|
* The bool query maps to Lucene BooleanQuery. It is built using one or more boolean clauses, |
|
9
|
|
|
* each clause with a typed occurrence. The occurrence types are: |
|
10
|
|
|
* |
|
11
|
|
|
* - "must" |
|
12
|
|
|
* The clause (query) must appear in matching documents and will contribute to the score. |
|
13
|
|
|
* |
|
14
|
|
|
* - "filter" |
|
15
|
|
|
* The clause (query) must appear in matching documents. However unlike must the score of the query will be ignored. |
|
16
|
|
|
* |
|
17
|
|
|
* - "should" |
|
18
|
|
|
* The clause (query) should appear in the matching document. In a boolean query with no must or filter clauses, one or |
|
19
|
|
|
* more should clauses must match a document. The minimum number of should clauses to match can be set using the |
|
20
|
|
|
* minimum_should_match parameter. |
|
21
|
|
|
* |
|
22
|
|
|
* - "must_not" |
|
23
|
|
|
* The clause (query) must not appear in the matching documents. |
