I appreciate the effort and I understand what you are saying but I do not understand how this can help me.
I am looking to build a search form that will look into 3 parameters, search typing, portfolio category and portfolio tags. I do not need to create extra fields because these options are already available on your plugin.
I went to General Options -> Sources and I selected Portfolio_page on the “Search in custom post types” panel. I also selected portfolio categories and portfolio tags on the source 2 page, on the Return taxonomy terms as results. What else do I need to do in order to make this search type appear? And also how can I have multiple boxes with these options, portfolio category and portfolio tags instead of simply one big search bar.
