Class org.apache.lucene.search.DocIdSetIterator

Examples of org.apache.lucene.search.DocIdSetIterator.cost()

org.apache.lucene.search.DocIdSetIterator.cost()
Returns the estimated cost of this {@link DocIdSetIterator}.
This is generally an upper bound of the number of documents this iterator might match, but may be a rough heuristic, hardcoded value, or otherwise completely inaccurate.
