Could you explain your response, please? Are you saying CUSTOM ADVANCED feature is possible and accessible through PAGE SET UP, or the only SEARCH form is that which comes as default built in theme? If you mean the later, know that many of us have really LOST the general use for the theme due to lack of custom search feature. Our site users cannot refine their search results by custom short-codes based on the listing type that we design the site for. Please, see if you can add options for us to define our own ADVANCED SEARCH for our users to refine their search results.
