While trying out 8.0-SNAPSHOT I get something strange. There is an exists query which gives true where the answer should be false. There is no dataset with @name='DiMu__abm', yet exists gives "true". The subsequent query shows what is actually in the XML.

Hi Gerald, Could you possibly provide me with a reproducible example? If that's not possible, I would be interested.. * in the query info * what happens if you rebuild the index * if you get a result when calling doc('narthex_dimcon/narthex_dimcon.xml')/narthex-datasets/dataset[@name='DiMu__abm'] Thanks, Christian

Hmm.. very interesting:
