The page we use for your search wrapper is http://www.yourdomain.com/mls-design.php. All pages, if they don't have a special content page set up, will use this page.
[MLS_BODY] is where the search will be inserted, and it is required.
We recommend adding, at minimum, a default title tag, and meta description. These will be used on any page that doesn't automatically replace them. Pages like property details pages will automatically generate their own title tag and meta description.
You can optionally add header tags and text. This content will be on all your search pages unless overwritten.
