Query DSL

Query DSL

edit

Elasticsearch provides a full Query DSL based on JSON to define queries. Think of the Query DSL as an AST 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 match, term or 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 bool or dis_max query), or to alter their behaviour (such as the not or constant_score query).

Query clauses behave differently depending on whether they are used in query context or filter context.
