I'm currently testing Lucene.Net, and it's perfect for my needs but I've seen this recent post in the dev mailing list (with no answers)... Do you think it's unsafe to start developping with this library ? I thought it was widespread used ?

A:
As far as I know Lucene.NET is used for RavenDB, so it should be in pretty good shape.
Also, it depends on what do you mean by "unsafe". It is hard to guarantee any OSS project will never stop, so all of them are inherently "unsafe". Same is actually true for commercial projects.
Lucene.NET seems to be a reliable project at current point (I used it in small project, so I can not guarantee that, but RavenDB seems to do just fine), so even if new development stops, it should still be possible to rely on it.
I think it all depends on longevity of your project, on your readiness to fix any issues in Lucene (if they arise), and on requirements of the project owners.
