WordPress API and the CATS Jobsite plugin

[da...@vets4work.com]

I am working with the WordPress API and the CATS Jobsite plugin has a SEARCH function on the Job Orders job listing. I would like to search by ID# in order to pull up a specific Job Order entry but the default SEARCH does not search that field. How do I add/modify the SEARCH function to broaden its search criteria to include ID# ?
