Good to hear because I started to experiment with it a couple months ago to solve a specific problem. I abandoned it because the embedded version required an older version of Lucene than I was using. Yes I could have worked around that but it's a lot of extra work to try something that may or may not solve my problem. Then I tried the server version which also required I be able to call web services (something my code had no other use for). Worked through that and found the performance pretty poor compared to embedded. I ended up just solving the problem in Lucene. Glad I didn't spend more time on it.

I would love to have a good graph database later on though
