If anyone has performed a forum search recently, you may have noticed the lightening fast response! We have implemented a new search engine called Sphinx. It's incredible how fast this thing is! Try it out!
What's even more amazing is that it now allows searching on two letter words. No more problems when searching for k1, j1, PR, etc. However, as with all good things, there's a few caveats....
There will now be a slight delay between a post being made and it showing in the index. This delay will be around 10 minutes or so. Secondly, the ordering of results may not be exactly in date order although a recent post will be given a higher weighting than older posts, it's not guaranteed that date ordering will be exact. This is exactly how most non-forum search engines work, including Google. Finally, a few of the more advanced and little used search features may not be available.
But even with these limitations, the ability to carry out two letter word searches and the amazing speed is more than worth it. Another side benefit is the reduced load that will be placed on the server when multiple people are searching. This will translate into faster performance throughout the site.
