I was recently searching around for a good enterprise search engine and wanted something OSS. I found Apache Lucene and so far I really like it. It's got documentation, a clear release schedule, and I know lots of other people use it. I was happy to hear that it's Apache because it probably means it won't die because one maintainer goes away. Maybe it's silly, but if I find a project is Apache it gives me a good feeling. Of course some of their projects die. That's OSS. But that's not something you can solve for. Even paid software goes away after awhile.
