search section not working

Hi,

  I have had a CMS Builder install for quite some time and things were working fine.  I got a report from the client that the search was not working on the backend.  This is to say that the section editor for our listings, on the searching tab, we have in there:

Listing Number|mls|match
_all_

Which in the past provided us with an "advanced search" link at the top of the listings, and then it would drop down and show the listing number box or the all search box.  This part still functions and the boxes appear and disappear if the advanced/basic search is toggled.  The issue is that no matter what you do when you hit the search button it returns all results.  If I select the 5,10, 20, listings per search result that works, but it still will always return ALL listings.  I am unsure how to debug this because I see nothing in the sites error log.

Any tips on how to narrow down this issue?

Thanks
