I was investigate your situation

U can search only by that fields which present in main table and relate table by ->set_relation('id_empresa','empresa','representante'), then search will work!

If u need more related field only one thing u can do - join all fields that u need in one column like

->set_relation('id_empresa','empresa','{representante} {telefono})  without custom model

in list column will be all in one and search u will make by only that column where u have multiplie values from related table!

 

 

Hope it helps

P.S. Maybe try another theme like datatables then u will not have such problem cause search not using ajax - all happens with JS

but the real solution is to find the way of modify the query that is executed when the form #filtering_form is submitted, for now i am going to add two more fields to my table "empresa" that takes the value of "id_empresa" automatically when insert data to be able to use set_relation() and then search will work! but i will have to modify my database and modify my model of data with unnecessary fields -_-

 

i am going to be investigating about this, if i find the solution I will communicate you :)
