Advanced Search

This is most likely a newbie question but I am using enfold and setting up a sortable product portfolio. For various reasons I like to “portfolio entry” option better than the “blog post for each product”. The site is to have various sections and in these sections I want to set up a search box that only applies to certain portfolio categories. i.e. the results will only be from the categories I choose. Is such a thing even possible, is there a plugin that I am missing that does this?

I have searched for days and can find only advanced search options that may allow me to filter by blog post category.

I saw that I can edit the search form.php but how to edit it is another matter.

Any help is appreciated.
