Reply To: Advanced Job Search categories
hi v.siuksteris, this kind of change will need you to have quite good knowledge about WordPress development.
i going to point you to where you can change it, but i will not be able to specifically give you code about it.
1. front end for filter, please go to jobplanet plugin > template > job > search-job-filter.php
$( document.body ).trigger( 'ajax_filter_search' );
3. and the last is, you will need to alter query of your result. go to jobplanet-plugin > lib > class-jeg-job.php
and on line 217, you can find build_job_seach_query. its query you need to alter.
