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

nexialys, I tryed the vbulletin search with the extra code etc... but it was still running down my server. I installed this hack and its back to working faster then ever On a large board its definately best to use this hack rather then vbulletins fulltext search.

That's my experience. That's why I'm still using this one.

hum... i see your points here... so the best system is the hack here, isn't it ?!

ok, then, if Erwin and some other posted different debugs, wouldn't it be cool to have a final version to date ?!

Erwin argues are the best i can read, but it seems complicated to read all the 12 pages to see if it's ok or not to do this ir that change... can someone post a final 2.3 version of this hack please?! and updated for vB 3.0.3 ??? because lines are changed a lot!

[ImportPassion]

well, erwin says his wasn't working for search this forum and search this thread, but it is for me, so i didn't do his updates.
the original works great for me.

Well, i try to install this hacks in a fresh 3.0.3 and is not really easy.

Can some one make some v 2.3 whit a good install instruccion and Erwin addon :P

[Nitesh]

Yeah the original 2.2 version of that hack works fine for me, but its a little tricky to do the file edits on search.php as some of the codes different. After messin about a bit its not too difficult to figure out

Which part are you stuck on?

the new 3.0.2+ version have already a part for the fulltext feature because it's now a feature of the board, BUT ... that feature is partial in 3.0.2... this hack have more changes to do with the code, so maybe someone can rewrite it to suite the new options ?!

i would make it, but i'm not ease with it... the best would be to take advantage of the new option of vB and activate this hack when fulltext is activated, and use the old code when it's not ... i've started to try it, but i don't understand the code really well... you guys have more experience on this search feature, i suppose this would help...

[cerebro]

/me vote for that!

hum.. why this thread was not updated for the last month or so ?! is there someone using it, or we have to forget about it ???

i'd like to see it working properly for 3.0.3, and with everything fixed... is it possible to find it ?!

thanks!

bumping for the pleasure of it... someone ???

just update the thread please!
