Note: the below is outdated, search was changed once again: A new search engine for Stack Exchange
For a few reasons, we recently changed the guts of how search works on our sites. If you keep up, you've probably read somewhere that we were using SQL Server Full Text Search. There are a few areas that utilize search that all got a replacement tonight:
- Search itself (box in the upper right)
- Related Questions (to the right of a question)
- Titles (when asking a question, this finds similar questions that may have already been asked)
We invite you to try it on all sites in the network, for example here's the search pages for the trilogy:
As with all the features we add, it's better with feedback, please use the search and post feedback here (quality, issues, good/bad results?). We'll be watching the next few days to make tweaks as we go. Of course, if you're able to break it, post that too - we'll be watching and adding awesome as fast as we can.
