getDocIdSet
public org.apache.lucene.search.DocIdSet getDocIdSet(org.apache.lucene.index.LeafReaderContext context, org.apache.lucene.util.Bits acceptDocs) throws IOException
Description copied from class:Filter
Creates aDocIdSet
enumerating the documents that should be permitted in search results. NOTE: null can be returned if no documents are accepted by this Filter.Note: This method will be called once per segment in the index during searching. The returned
DocIdSet
must refer to document IDs for that segment, not for the top-level reader.- Specified by:
getDocIdSet
in classFilter
- Parameters:
context
- aLeafReaderContext
instance opened on the index currently searched on. Note, it is likely that the provided reader info does not represent the whole underlying index i.e. if the index has more than one segment the given reader only represents a single segment. The provided context is always an atomic context, so you can callLeafReader.terms(String)
on the context's reader, for example.acceptDocs
- Bits that represent the allowable docs to match (typically deleted docs but possibly filtering other documents)- Returns:
- a DocIdSet that provides the documents which should be permitted or
prohibited in search results. NOTE:
null
should be returned if the filter doesn't accept any documents otherwise internal optimization might not apply in the case an emptyDocIdSet
is returned. - Throws:
IOException
