I haven't tried it, because right now my indexing code barfs on an empty string, so there are no empty strings in the index. I'll need to manually put a document in the index and try that. A possible further complication: The field is whitespace tokenized and multivalued, where one value may be the empty string but other values could be non-empty strings. Thanks, Shawn
