Fulltext boolean search v.2.2 for vB

Hello all!

Moving here from beta forum
https://vborg.vbsupport.ru/showthread.php?t=62218

This hack makes nearly same for vB3 as
[vB 2.2.x] - Mysql 4 Search hack
https://vborg.vbsupport.ru/showthread.php?t=51716
for vB2

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

History:

I already found it. I just thought it would be easier posting the link instead of reading through a bunch of "I couldn't find it" messages.

I just tryed the mysql search hack that comes with the new 3.0.2.... crashed my computer lol... So im coming back to this hack, I was wondering when will the next update be with all the optimisations in the thread?

Thank you

@Nitesh... FullText Search is NOW integrated to vB 3.0.2 and 3.0.3 ... so it's useless to add this hack... you will simply trash your installation.
you need to take the SQL query found in your Options screen to enable the Search in FullText... because there is a special feature to add to sql, the FULLTEXT thing... it may be the reason your installation trashed.

bleh, vb one didn't work for me. had to go back to this one, and yes i changed the admin hidden options. Not sure if vb.com has it enabled, but if they do, it doesn't work for "search this thread". that was a few days ago.
