== Match All Query

The most simple query, which matches all documents, giving them all a `_score`
of `1.0`.

[source,js]
--------------------------------------------------
{ "match_all": {} }
--------------------------------------------------

The `_score` can be changed with the `boost` parameter:

[source,js]
--------------------------------------------------
{ "match_all": { "boost" : 1.2 }}
--------------------------------------------------

[[query-dsl-match-none-query]]
[float]
== Match None Query

This is the inverse of the `match_all` query, which matches no documents.

[source,js]
--------------------------------------------------
{ "match_none": {} }
--------------------------------------------------

Query DSL: Remove filter parsers. This commit makes queries and filters parsed the same way using the QueryParser abstraction. This allowed to remove duplicate code that we had for similar queries/filters such as `range`, `prefix` or `term`. 2015-05-05 02:27:52 -04:00			`== Match All Query`

Docs: Add query to Query DSL documentation We already introduced the MatchNoneQueryBuilder query that does not return any documents, mainly because we needed it for internal representation of the NONE option in the IndicesQueryBuilder. However, the query was requested at least once also for the query dsl, and since we can parser it already we should document it as `match_none` query in the relevant reference docs as well. 2015-11-02 06:57:35 -05:00
