selectEntity
Description copied from interface:SearchQuerySelectStepSelect the entity was originally indexed as a representation of the search hit for each matching document.The entity will be loaded directly from its original source (relational database, ...).
- Specified by:
selectEntityin interfaceElasticsearchSearchQuerySelectStep<R,E, LOS> - Specified by:
selectEntityin interfaceSearchQuerySelectStep<ElasticsearchSearchQueryOptionsStep<E,LOS>, R, E, LOS, ElasticsearchSearchProjectionFactory<R, E>, ElasticsearchSearchPredicateFactory> - Returns:
- The next step.
- See Also:
-
selectEntityReference
Description copied from interface:SearchQuerySelectStepSelect a reference to the entity that was originally indexed as a representation of the search hit for each matching document.Entity references are instances of type
EntityReference, but some mappers may expose a different type for backwards compatibility reasons.EntityReferenceshould be favored wherever possible as mapper-specific types will eventually be removed.- Specified by:
selectEntityReferencein interfaceElasticsearchSearchQuerySelectStep<R,E, LOS> - Specified by:
selectEntityReferencein interfaceSearchQuerySelectStep<ElasticsearchSearchQueryOptionsStep<E,LOS>, R, E, LOS, ElasticsearchSearchProjectionFactory<R, E>, ElasticsearchSearchPredicateFactory> - Returns:
- The next step.

select
Description copied from interface:SearchQuerySelectStepSelect an object projection as a representation of the search hit for each matching document.- Specified by:
selectin interfaceElasticsearchSearchQuerySelectStep<R,E, LOS> - Specified by:
selectin interfaceSearchQuerySelectStep<ElasticsearchSearchQueryOptionsStep<E,LOS>, R, E, LOS, ElasticsearchSearchProjectionFactory<R, E>, ElasticsearchSearchPredicateFactory> - Type Parameters:
P- The resulting type of the projection.- Parameters:
objectClass- The type of objects returned by the projection. The class is expected to be mapped (generally through annotations) in such a way that it defines the inner projections.- Returns:
- The next step.
- See Also:

select
public <P> ElasticsearchSearchQueryWhereStep<P,LOS> select(Function<? super ElasticsearchSearchProjectionFactory<R, E>, ? extends ProjectionFinalStep<P>> projectionContributor) Description copied from interface:SearchQuerySelectStepSelect a given projection as a representation of the search hit for each matching document.- Specified by:
selectin interfaceElasticsearchSearchQuerySelectStep<R,E, LOS> - Specified by:
selectin interfaceSearchQuerySelectStep<ElasticsearchSearchQueryOptionsStep<E,LOS>, R, E, LOS, ElasticsearchSearchProjectionFactory<R, E>, ElasticsearchSearchPredicateFactory> - Type Parameters:
P- The resulting type of the projection.- Parameters:
projectionContributor- A function that will use the factory passed in parameter to create a projection, returning the final step in the projection DSL. Should generally be a lambda expression.- Returns:
- The next step.

select
Description copied from interface:SearchQuerySelectStepSelect a projection as a representation of the search hit for each matching document.- Specified by:
selectin interfaceElasticsearchSearchQuerySelectStep<R,E, LOS> - Specified by:
selectin interfaceSearchQuerySelectStep<ElasticsearchSearchQueryOptionsStep<E,LOS>, R, E, LOS, ElasticsearchSearchProjectionFactory<R, E>, ElasticsearchSearchPredicateFactory> - Type Parameters:
P- The resulting type of the projection.- Parameters:
projection- A previously-createdSearchProjectionobject.- Returns:
- The next step.
- See Also:
-
select
Description copied from interface:SearchQuerySelectStepSelect a list of projections as a representation of the search hit for each matching document.Note that using this method will force you to use casts when consuming the results, since the returned lists are not typed (
List<?>instead ofList<T>). You can replace calls to this method advantageously with calls toSearchQuerySelectStep.select(Function)defining acomposite projection.- Specified by:
selectin interfaceElasticsearchSearchQuerySelectStep<R,E, LOS> - Specified by:
selectin interfaceSearchQuerySelectStep<ElasticsearchSearchQueryOptionsStep<E,LOS>, R, E, LOS, ElasticsearchSearchProjectionFactory<R, E>, ElasticsearchSearchPredicateFactory> - Parameters:
projections- A list of previously-createdSearchProjectionobjects.- Returns:
- The next step.

-
where
Description copied from interface:SearchQueryWhereStepSet the predicate for this query.- Specified by:
wherein interfaceSearchQueryWhereStep<ElasticsearchSearchQueryOptionsStep<E,LOS>, E, LOS, ElasticsearchSearchPredicateFactory> - Parameters:
predicate- ASearchPredicateobject obtained from the search scope.- Returns:
- The next step.
-
where
public ElasticsearchSearchQueryOptionsStep<E,LOS> where(Function<? super ElasticsearchSearchPredicateFactory, ? extends PredicateFinalStep> predicateContributor) Description copied from interface:SearchQueryWhereStepSet the predicate for this query.- Specified by:
wherein interfaceSearchQueryWhereStep<ElasticsearchSearchQueryOptionsStep<E,LOS>, E, LOS, ElasticsearchSearchPredicateFactory> - Parameters:
predicateContributor- A function that will use the factory passed in parameter to create a predicate, returning the final step in the predicate DSL. Should generally be a lambda expression.- Returns:
- The next step.
-
where
public ElasticsearchSearchQueryOptionsStep<E,LOS> where(BiConsumer<? super ElasticsearchSearchPredicateFactory, ? super SimpleBooleanPredicateClausesCollector<?>> predicateContributor) Description copied from interface:SearchQueryWhereStepSet the predicate for this query.- Specified by:
wherein interfaceSearchQueryWhereStep<ElasticsearchSearchQueryOptionsStep<E,LOS>, E, LOS, ElasticsearchSearchPredicateFactory> - Parameters:
predicateContributor- A consumer that will use the factory passed in parameter to create predicates and add them as clauses to the collector passed in parameter. Should generally be a lambda expression. The resulting root predicate will have to match all clauses.- Returns:
- The next step.
