You will need MySQL server v4.0.1 or better (but sometimes it may work on 3.23.xx). After installing you will be able to search with empty native vB index (word and postindex tables) and using modifiers.
Allowed modifiers + are ,-, * and "
All modifiers except * should be used only once for one word (in the beginning and without space).
* it should be used at the end of a word.
For example:
windows unix -> will find messages containing at least one these words.
+windows +unix -> will find messages with both this words.
windows* -> will find "windows", "windowss", "windowssauce" or "windowst".
*indows will NOT find "windows"
"some words" -> will find "some words of wisdom", but will not find "some extra words".
Search phrase length limitations replaced with results number limitation.
Value of old "Search Index Maximum Word Length" used to limit number of posts in the result returned by fulltext search (control panel/Message Searching Options)
Supposed that it must run faster then native vB search

Has anyone considered rewriting this for 3.6.5? The built in fulltext search is horrible and the sphynx search has it's issues (sorting by date, etc). When we were running this search on 3.0.9 searches returned within seconds. Now with the fulltext search it can take upwards of a minute if a search is done on all posts - >1.5 million posts. That's with running the searches on a slave server that's just handling searches.
