The search system has been improved. Here are the visible changes:

1) You can now search for most 3-letter words in posts (not topics).

2) Searches should return full result sets (as opposed to limited results that was imposed some months ago for performance reasons)

3) Searches for popular terms should not stall the forum for the other users anymore.

4) Search cooldown has been relaxed to 15 seconds.

5) Simple search has been retired. Use advanced search instead.

Full technical details may be posted to our development blog later on.
