This is one of the things that Stack Overflow and the rest of the sites that run on this platform do very well. As soon as you try to create a new question, a little window is shown that shows other similar questions. How is this done? What technology can be used to achieve this? Lucene, Sphinx, ...?

StackOverflow (and StackExchange in general) uses Lucene.net for full-text search.

Might want to read this as well.

  • Thanks, I guess the algorithm doesn't work that well since it didn't show that as a similar question hehe – Drew Mar 06 '11 at 03:14

    It works great, but it's restricted by the keywords that you type in. If you (or others before you) are bad at choosing question titles, the search feature won't work all that well for you. – Cody Gray - on strike Mar 06 '11 at 05:25
