MatchAllPredicateOptionsStepImpl

public MatchAllPredicateOptionsStepImpl(SearchPredicateDslContext<?> dslContext,
 SearchPredicateFactory factory)

Method Details

boost

public MatchAllPredicateOptionsStep<?> boost(float boost)

Description copied from interface: PredicateScoreStep

Boost the weight of the predicate in score computation.

Specified by:

boost in interface PredicateScoreStep<MatchAllPredicateOptionsStep<?>>

Parameters:

boost - The boost factor. Higher than 1 increases the weight in score computation, between 0 and 1 lowers the weight. Lower than 0 is for experts only.

Returns:

this, for method chaining.

constantScore

public MatchAllPredicateOptionsStep<?> constantScore()

Description copied from interface: PredicateScoreStep

Force the score of the predicate to a single constant, identical for all documents.

By default, the score will be 1.0f, but boosts, if any, will still be applied to the predicate.

Specified by:

constantScore in interface PredicateScoreStep<MatchAllPredicateOptionsStep<?>>

Returns:

this, for method chaining.

except

public MatchAllPredicateOptionsStep<?> except(SearchPredicate searchPredicate)

Description copied from interface: MatchAllPredicateOptionsStep

Add a "must not" clause based on a previously-built SearchPredicate,

Documents matching the "must not" clause won't match the "match all" predicate.

Specified by:

except in interface MatchAllPredicateOptionsStep<MatchAllPredicateOptionsStep<?>>

Parameters:

searchPredicate - The predicate that must not match.

Returns:

this, for method chaining.

except

public MatchAllPredicateOptionsStep<?> except(Function<? super SearchPredicateFactory,? extends PredicateFinalStep> clauseContributor)

Description copied from interface: MatchAllPredicateOptionsStep

Add a "must not" clause to be defined by the given function.

Best used with lambda expressions.

Documents matching the "must not" clause won't match the "match all" predicate.

Specified by:

except in interface MatchAllPredicateOptionsStep<MatchAllPredicateOptionsStep<?>>

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.

build

protected SearchPredicate build()

Specified by:

build in class AbstractPredicateFinalStep
