The basic search (Lyrics & Knowledge Search, with a single input field on the front page) is impressively quick. But can return many false results.

For example a search for 'minimal' returns 'more that 1000' matches. But that includes posts that contain minimalism, minimize, minimized, minim (lots of those), mini-me, and many other variants. I don't know whether that's a bug or a feature. I tried search terms such a 'minimal NOT minim' and 'minimal AND NOT minim' but didn't get a convincing set of results with just 'minimal'.

Perhaps more important is whether it finds all posts containing a search term. That would require much more more testing to discover.

The advanced search always gives me a 500 - Internal server error.
