Nevermind - sort of - I think I found this in the Site Config - it SEEMS to be working. I just set it to search by Square Feet. I just hope it will keep the property categories together instead of them running home sales into rentals etc. in the search results.

I have never set up an OR search at all. I've tried the documentations but I can't find anything on this and I'm fairly certain it's because I don't know what to look for.

Here is the main page for the search:
which are all hard coded into the template.

If you click them you will see that the link to search only shows the properties for that specific category. Once the folks reach the page showing the available properties, they want the properties to be ordered for viewing the list by square feet (smallest to largest).

Is this possible? If so, can someone point me instructions for doing this or tell me what I need to do? Thanks!
