Adrien Grand created LUCENE-5115: ------------------------------------ Summary: Make WAH8DocIdSet compute its cardinality at building time and use it for cost() Key: LUCENE-5115 URL: https://issues.apache.org/jira/browse/LUCENE-5115 Project: Lucene - Core Issue Type: Improvement Reporter: Adrien Grand Assignee: Adrien Grand Priority: Minor
DocIdSetIterator.cost() accuracy can be important for the performance of some queries (eg.ConjunctionScorer). Since WAH8DocIdSet is immutable, we could compute its cardinality at building time and use it for the cost function. -- This message is automatically generated by JIRA.
