It seems the search function on the site is broken.

If I enter a phrase in the search box, it does return results.
However, leave the box blank and click search to get the advanced options, and no matter what I put in, it came up with 'Sorry - no matches. Please try some different terms. '

Just to be sure, I entered the term php in the advanced search and selected the PHP forum, and again, no results.

Also, the dropdown to save/clear preferences always alerts 'Seach Preferences Saved' regardless of which option is chosen :)

Yup, it's down. Working on resolving it :)
