| Methods Summary |

| public void | add(org.apache.lucene.index.IndexReader reader)Add an IndexReader.

| public void | add(org.apache.lucene.index.IndexReader reader, boolean ignoreStoredFields)Add an IndexReader whose stored fields will not be returned. This can
accellerate search when stored fields are only needed from a subset of
the IndexReaders.
