OK, i'll try: (This is obviously a big topic) This database is a topic map for for several software domains: Ruby, javascript, erlang, .. There are 4 levels to the topic map hierarchy, so you'll see 4 headings on the left, separated by "_,_". I've run this database through several fulltext search engines. The only one active and returning hits at present is Sphinx, since this is running on a pretty low-memory VPS. Ignore the other sections. Essentially the difference between this search and, say, google, is that all of the words entered in the query must match a database record for that record to be returned as a hit. This is different from Google, which will return documents matching only some query terms. I think this returns quick feedback to the user that either they need to change query terms, or that topic is simply not covered in the database.
