We installed a new search back end to the wiki at
The Lucene search engine is the same search engine used by Wikipedia, and, as every knows, you can always find out what you want to know on Wikipedia.
The new search has "search suggestions," "Did you mean", and generally operates like you expect a search engine to work. We hope this will help make the wiki more useful to everyone. There is quite a lot of documentation there, and now it will be much easier to find.
