I my odoo app a have two models "contract" and "contract_line". Each contract has a One2many field (contract_line_ids) meaning that each contract has a list o many contract lines.
In the contract I have represented that one2many contract_line_ids as a tree view inside the form. The problem is that a contract has too many contract line and is dificult to locate a specific contract line. So I need to implement a search box, or any other way to filter those contract lines inside "contract" that matches ans specific condition (ex search the contract_line with ans specific name, cod etc.)
How do I implement a search mechanism for that One2many field?
