Hi, I have to create a field within the form of a customer (company type) which functions as a search engine, the idea is to place the name of an individual contact that is related to the company in which it is located and pressing a "search" button can only see the contacts with that name (Example: search for "Nicole Ford" within the view of the contact "Azure Interior"). This is because we have client companies that have many registered contacts and it is complicated to search in the kanban view that has the form of a client with their contacts.

Try via odoo studio to access the xml view of a customer (res.partner.form) and add the search engine using this code to create the field:

In this example you can see that the above code placed in the res.partner.form it does create the search box, but it doesn't actually work and when you click "search" you get an error.

I accept any suggestion
