Multiple Search Field Types in a Portal
I am trying to do a musical search return in a portal. I have several filed types (4 in total) to narrow the search:
Two that are pull down menus based upon a related db (Genre and Tempo)
Two that are open and contain several text data results which are separated by a comma (Keywords and Instrumentation) and the fields could contain: Keywords: (poignant, groove, reflective) or Instrumentation (guitar, bass, drums)
I want the user to use as many or as little of the 4 fields to get the result and have it update automatically.
How do I do that?
