My search function doesn't work...

The search function in my forum isn't working. Even when I type in words that I know have been used multiple times in posts, I keep getting the message "No topics or posts met your search criteria". Any help or suggestions for a solution would be much appreciated.

thanks.

The search option only searches in topic titles not in posts.

Even if I search for words that have been used in topic titles, there still aren't any results.

I've also gone to "advanced seach" and selected "posts" instead of "topics" with no luck.

Thanks for your response.

Any other ideas?
