Hello. Thank you for contacting the Toolset support.
I woudld like to know you set your view to query what post type - Organization or Jobs?
Also, how you want to display the parent taxonomy filter - as select dropdown?
If you can share admin access details and problem URL once I review your current structue I will be able to guide you in the right direciton.
*** Please make a FULL BACKUP of your database and website.***
I would also eventually need to request temporary access (WP-Admin) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.
I have set the next reply to private which means only you and I have access to it.
I see you added two taxonomy filters where one taxonomy (filter) is attached to organization post type and another taxonomy (filter) is attached to Jobs post type.
Do you want to keep both taxonomy fitlers "Sector of Activities" and "Type of Jobs"?
Actually, you can create a custom search view and add the filters for the custom fields, taxonomies for the post type you set to query.
To filter parent/child posts using the same view is not recommended because you can not add the parent frontend filters to the child view or viceaversa.
If you set your view to query "job" post type, then you can add filters using custom fields and taxonomy that are belongs to post type "job". But this will give you luxury to display related parent informtion for every job post as you have one-to-many post relationship with organizations and jobs post type.
Yes - but the catch here is that if you set your view to query post type "Jobs" then you can able to add custom search filter using custom fields and taxonomy belongs to post type "jobs". you will not be able to add search filters for custom fields and taxonomy for post type organizations.
