Hi OrientDB team,
First of all, thanks for your quick response and having a new
Orientdb-lucene release out.
We are trying out the latest Orientdb-lucene release
(oreintdb-lucene-1.7.0-dist.jar) in Orientdb-1.7.10. I had the impression
that Orientdb-lucene was doing stemming, but tests show it doesn't do
stemming. Is this the expected behaviour or did I do anything wrong? Bellow
are my tests. It shows I only get results when there is an exact match.
