Altering the ajaxsearch 1.9 beta filtering with TVs using a check box selection

I understand how the filtering function works in the beta of Ajaxsearch.

Problem is, I want this to be user editable.

Scenario: Job site, users need to filter by category (tv called vaccategory) and location (tv called vaclocation), ideally in a checkbox format (so multiple TVs can be selected)

I am thinking I might have to use some javascript to dynamically change the ajaxsearch call but to be honest I have no idea where to start.

Any ideas?

thanks in advance

Nay mind, looks like tvExplorer is a far better solution to this.
