If I create a custom computed field through the Odoo UI (Settings > Technical > Fields), is it possible to make this field searchable? If I were doing this on-premise via Python code, I would just add a search parameter to the field definition which would return a domain used to search the database. That's explained pretty clearly in the docs:
https://www.odoo.com/documentation/10.0/reference/orm.html#fields
However, I am using an instance of Odoo SaaS, and I don't see any way through the UI to define the search method. Is it possible? What about through an XML data file?
