Multiple DataAssist Search / Results function

I'm building a website for a client that want to be able to search multiple categories i.e. Clothing Lines, or description, or Rep etc. I've built a simple drop down that will open a new link i.e. "Search Line" etc. From the "Search Line" page I would like to create a search function that searches only the "Clothing lines" data portion of my database. I would like to duplicate this feature on each of the other corresponding pages as well i.e. a separate search on the "Description" page and or the Rep's page.

This is a link to the sample page: searchlineSEARCH.php
the results page is: searchlineRESULTS.php

the results are at the bottom of the page, I haven't placed them in the body yet

OK, so you have 4 results pages with the search form:
searchall.php
searchcategory.php
searchline.php
searchrep.php


On each of the pages, in the DataAssist search behavior, create a KeyWord search that uses the desired column.

For example on the searchline page page, set the Key Word search to use the Clothing line column.

On the searchcategory page, set the key word search to use the category column.
