Class AcceptLiveDocsFilter

java.lang.Object
  org.apache.lucene.search.Filter
      com.atlassian.confluence.search.lucene.filter.AcceptLiveDocsFilter

public class AcceptLiveDocsFilter
extends org.apache.lucene.search.Filter

Wraps a delegate Filter and ensures that only live (non-deleted) docs are accepted through this filter. This should typically be applied over the filter that we plan to search with as a catch-all. Ideally, all clients implementing a filter would follow the best practice of wrapping their DocIdSets in a call to BitsFilteredDocIdSet.wrap(org.apache.lucene.search.DocIdSet, org.apache.lucene.util.Bits). However, we cannot enforce this.
