Can we customize the filters? Search boxes? and the search results?

Hello team,

The requirements are
- Customize the search filters from the default to search by province->city->district, and these data are maintained, uploaded by ourselves.
- Customize the search result table, the thing needs to be changed are the "download" icon, we will predefine if the file (mostly PDFs) is downloadable or not. The download icon shows only when the file is downloadable.

Guess we can accomplish these by using the Crocoblock's Smartfilter, but I wonder if it can be done by your plug-in directly?
