hi Laura!
you are right. "it looks like your tables in your database have varying collations." I am almost possitive this is the problem, but I don't know what the default collation is for drupal, especially that my site has arabic, which might be an issue here. I know for certain that whatever collation is the default works, because whenever I setup a new drupal site I have no problem. this particular site was transformed from host to another, and from mysql 4.0 to mysql 5.27. there's a known issue with utf when upgrading. I solved that in part, it seems, because my site performs so well aside from this search problem. how do I change the collation? it looks it's not an easy task for someone like me, who's not a mysql expert.
thanks.

I am not a mysql expert, but it looks like your tables in your database have varying collations. They should all be using the same collation. utf8_general_ci has worked for us, but maybe either would be fine. I don't know.
There are several forum discussions on ways you can fix this, which some Googling should bring up for you. You will also want to make sure your default collation matches, so that when you install new modules and/or updates, you don't end up with mixed tables again.
Again, I am not a mysql expert, so I may be wrong here.

hi.
I am noticing a very wierd problem at my website, each time I try to search, either as guest or authenticated user, I get the following error:
• user warning: Illegal mix of collations (utf8_unicode_ci,IMPLICIT) and (utf8_general_ci,IMPLICIT) for operation '=' query: do_search CREATE TEMPORARY TABLE temp_search_results SELECT i.type, i.sid, 5 * (9.71305588655

I tried to "reindex" but that didn't work. I read in the forums about a similar wierd issue but it wasn't about search in particular.
any clues?
the site url is: www.nattiq.com you may want to see www.nattiq.com/ en as the default language is arabic.
