C# 클래스 Lucene.Net.Search.FilteredDocIdSet

Abstract decorator class for a DocIdSet implementation that provides on-demand filtering/validation mechanism on a given DocIdSet.

Technically, this same functionality could be achieved with ChainedFilter (under queries/), however the benefit of this class is it never materializes the full bitset for the filter. Instead, the #match method is invoked on-demand, per docID visited during searching. If you know few docIDs will be visited, and the logic behind #match is relatively costly, this may be a better way to filter than ChainedFilter.
