Creates a 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.
