Search engine problem

[sergarch]

Hello there!

I moved my site to GoDaddy shared hosting and have find some weird problem with search engine.

Mainly we are using Russian language as dafault.

The problem is that vBulletin's search engine on my forum do not recognize russian letters.

For example, when we enter some keywords in Russian in the search field - it returns nothng, but when we serching with English letters (such as nicknames) - it works perfectly.

Our forum using UTF-8, and all DB's is in utf8_general_ci

I rebuilded search index via vBulletin's adminCP with no results.
I uncommetted // $config['Mysqli']['charset'] = 'utf8'; and //define('DISABLE_HOOKS', true); - no luck.
I switched from custom to dafault style - no results.

I understand, that it is an encoding problem somewhere, but I don't know where and what to do.

Please advise me how to solve it!
