get

public Scorer get(long leadCost)

Description copied from class: ScorerSupplier

Get the Scorer. This may not return null and must be called at most once.

Specified by:

get in class ScorerSupplier

Parameters:

leadCost - Cost of the scorer that will be used in order to lead iteration. This can be interpreted as an upper bound of the number of times that DocIdSetIterator.nextDoc(), DocIdSetIterator.advance(int) and TwoPhaseIterator.matches() will be called. Under doubt, pass Long.MAX_VALUE, which will produce a Scorer that has good iteration capabilities.

cost

public long cost()

Description copied from class: ScorerSupplier

Get an estimate of the Scorer that would be returned by ScorerSupplier.get(long). This may be a costly operation, so it should only be called if necessary.

Specified by:

cost in class ScorerSupplier
