Form search query – displaying ACF “Post Object” field as results

I will try to summarize as simply as possible my request.

I have a custom post type (CPT) called “job”.
This custom post type includes 3 fields :

I would like to create a custom wordpress search page/form who allows user to type the name of a job (including secondary title) and display the linked jobs as results.

I tried many things with this ressource : https://www.advancedcustomfields.com/resources/query-posts-custom-fields/

But i didn’t succeed to do it.

Any advices are welcome !

Thanks for reading me.
