[havard20009]

hi guys
i have problem with fulltext search
when i`m using fulltext search i cnat search any mor
and no more result
when i`m using vbulletin search its ok
what can i do ??
and also i checked this one and i cant resolve my problem

[B]Admin CP -> Forums & Moderators -> Forum Manager -> Edit Forum -> Index New Posts in Search Engine[/B]

Also note that searches also use group permissions. If a user doesn't have access to view threads in a specific forum then the search will not find any results in that forum.

Also check which search engine you are using:

[B]Admin CP -> vBulletin Options -> Search Type (on the left, not the right)[/B]

If you are using fulltext then run a repair to ensure that the search index is up-to-date:

[B]Admin CP -> Maintenance -> Repair / Optimize Tables[/B]

If you are using the vBulletin search engine then you can run a rebuild in your:

[B]Admin CP -> Maintenance -> Update Counters -> Rebuild Search Index[/B]

this result for Fix Unique Indexes

I see your site is in Persian. Do you have this problem with all search terms or just Persian? For example, try making a post in English and run a search for one of the English words.

3 letter words like that are often below the minimum word length. For fulltext the minimum word length is a MySQL setting on the server which needs to be set by your host:

After changing this MySQL setting you need to run a repair to update the indexes:

Admin CP -> Maintenance -> Repair / Optimize Tables

I have dealt with search problems with multibyte languages before. They are often caused by the UTF-8 characters being stored as entities because of incorrect language settings on the forum. This thread has several settings you can check:

http://www.vbulletin.com/forum/showthread.php?t=259250

Especially check #1. This should be UTF-8.

After fixing the language settings then new posts should be searchable, but there is no easy way to fix the old posts.
