Improvements have been made to the search engine:

- Changed fulltext indexer from MySQL to Sphinx, using Prolag's Sphinx IPB mod. Results can be obtained much faster and without slowing everyone else down, while being as reliable or better as the previous method. We hope
- Word length cutoff reduced to 2 (from 3)
- Search cooldown period reduced to 10 seconds (from 15)

Please let us know through the feedback forum if you encounter any difficulties. Cheers
