Using Java Builders

The Java High Level REST Client depends on the Elasticsearch core project which provides different types of Java Builders objects, including:

Query Builders: The query builders are used to create the query to execute within a search request. There is a query builder for every type of query supported by the Query DSL. Each query builder implements the QueryBuilder interface and allows to set the specific options for a given type of query. Once created, the QueryBuilder object can be set as the query parameter of SearchSourceBuilder. The Search Request page shows an example of how to build a full search request using SearchSourceBuilder and QueryBuilder objects. The Building Search Queries page gives a list of all available search queries with their corresponding QueryBuilder objects and QueryBuilders helper methods.
Aggregation Builders: Similarly to query builders, the aggregation builders are used to create the aggregations to compute during a search request execution. There is an aggregation builder for every type of aggregation (or pipeline aggregation) supported by Elasticsearch. All builders extend the AggregationBuilder class (or PipelineAggregationBuilder`class). Once created, `AggregationBuilder objects can be set as the aggregation parameter of SearchSourceBuilder. There is a example of how AggregationBuilder objects are used with SearchSourceBuilder objects to define the aggregations to compute with a search query in Search Request page. The Building Aggregations page gives a list of all available aggregations with their corresponding AggregationBuilder objects and AggregationBuilders helper methods.
