Why search option don't search post only topic's title?

I have a forum, and when use a search option, for searching some text, a don't get any find post (post have the search text, but search can't find!), only if the text have in title of the topic, not in the post text, than search option find a topic.

The search option works only for the topic titles not for what is written in the post.

OK, that is true. Thank you.

You're welcome!
