Elasticsearch provides a full Query DSL (Domain Specific Language) based on JSON to define queries.
|
|
Think of the Query DSL as an AST (Abstract Syntax Tree) of queries, consisting of two types of
|
|
clauses:
|
|
|
|
Leaf query clauses::
|
|
|
|
Leaf query clauses look for a particular value in a particular field, such as the
|
|
<<query-dsl-match-query,`match`>>, <<query-dsl-term-query,`term`>> or
|
|
<<query-dsl-range-query,`range`>> queries. These queries can be used
|
|
by themselves.
|
|
|
|
Compound query clauses::
|
|
|
|
Compound query clauses wrap other leaf *or* compound queries and are used to combine
|
|
multiple queries in a logical fashion (such as the
|
|
<<query-dsl-bool-query,`bool`>> or <<query-dsl-dis-max-query,`dis_max`>> query),
|
|
or to alter their behaviour (such as the
|
|
<<query-dsl-constant-score-query,`constant_score`>> query).
|
|
|
|
Query clauses behave differently depending on whether they are used in
|
|
<<query-filter-context,query context or filter context>>.
