public DocIdSet getDocIdSet(IndexReader reader) throws IOException
Filter
DocIdSet
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.
getDocIdSet

represent the whole underlying index i.e. if the index has more than
one segment the given reader only represents a single segment.
