Here's how you can add a custom search method to enable searching on a computed field in Odoo. This approach avoids the need to store the computed field in the database. from odoo import api, fields, models class ProductTemplate(models.Model): _inherit = 'product.template' price_with_tax = fields.Float( compute="_compute_price_with_tax", search="_search_price_with_tax" ) @api.depends('list_price', 'taxes_id') def _compute_price_with_tax(self): for product in self: tax_rate = sum(product.taxes_id.mapped('amount')) / 100 product.price_with_tax = product.list_price * (1 + tax_rate) def _search_price_with_tax(self, operator, value): tax_ids = self.env['account.tax'].search([]) tax_rate = sum(tax_ids.mapped('amount')) / 100 adjusted_value = value / (1 + tax_rate) return [('list_price', operator, adjusted_value)]
