Hi,
Currently, no code documentation for this widget.
If you want to customize, you can find to the following file and functions:
1, Part settings and display in the frontend
wp-content/themes/noo-jobmonster/widgets/widgets.php and find to the class "Noo_Advanced_Company_Search_Widget"
2, Resume query (results are always returned on the resume archive page):
wp-content/themes/noo-jobmonster/framework/resume/resume-query.php and find to these functions:
http://prntscr.com/qa4h4p
Note: All locations that use "Search Resume" run through these functions.
Best regards,
tb.
