Sarah Moyer from Schoolwires gave me this code which is used to embed minibase results onto a flex page.  App ID is the minibase ID that can be found by inserting a minibase into a flex app.  Field will be the field being searched on.  You can find the code for the field by going to minibase options, custom view and pulling the field into the editor.  After the field code you enter the category you want to be displayed.
