AggregationFilterStep (Hibernate Search 6.0.11.Final)

Type Parameters:

S - The "self" type (the actual exposed type of this step)

PDF - The type of factory used to create predicates in filter(Function).

All Known Subinterfaces:

RangeAggregationOptionsStep<S,PDF,F,A>, RangeAggregationRangeMoreStep<S,N,PDF,F>, TermsAggregationOptionsStep<S,PDF,F,A>
```
public interface AggregationFilterStep<S,PDF extends SearchPredicateFactory>
```
The step in an aggregation definition where a filter can be set to select nested objects from which values will be extracted for this aggregation.

- Method Detail
  - filter
```
S filter(SearchPredicate searchPredicate)
```
    Filter nested objects from which values will be extracted for this aggregation.
    The filter is based on a previously-built SearchPredicate.
    
    Parameters:
    
    searchPredicate - The predicate that must match.
    
    Returns:
    
    this, for method chaining.
  - filter
```
S filter(Function<? super PDF,? extends PredicateFinalStep> clauseContributor)
```
    Filter nested objects from which values will be extracted for this aggregation.
    The filter is defined by the given function.
    Best used with lambda expressions.
    
    Parameters:
    
    clauseContributor - 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:
    
    this, for method chaining.
  - filter
```
default S filter(PredicateFinalStep dslFinalStep)
```
    Filter nested objects from which values will be extracted for this aggregation.
    The filter is based on an almost-built SearchPredicate.
    
    Parameters:
    
    dslFinalStep - A final step in the predicate DSL allowing the retrieval of a SearchPredicate.
    
    Returns:
    
    this, for method chaining.
