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
rangequeries. 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
dis_maxquery), or to alter their behaviour (such as the
Query clauses behave differently depending on whether they are used in query context or filter context.
