Hi,

In Odoo 19, your issue happens because the /shop page uses AJAX and OWL rendering, which reloads product results after your controller runs. Even though your Python filtering works, the frontend replaces your filtered list with the default one.

The proper fix is to override Odoo’s search domain before products are loaded instead of re-rendering the template. By customizing the _get_search_domain() method, you can apply whole-word filtering that works with Odoo’s frontend logic.

Try the following code.

# -*- coding: utf-8 -*-

import re

import logging

from odoo import http

from odoo.http import request

from odoo.addons.website_sale.controllers.main import WebsiteSale

_logger = logging.getLogger(__name__)

class CustomWebsiteSearch(WebsiteSale):

    def _get_search_domain(self, search, category, attrib_values, search_in_description=True):

        domain = super()._get_search_domain(search, category, attrib_values, search_in_description)

        if search:

            pattern = r'\b' + re.escape(search.lower()) + r'\b'

            products = request.env['product.template'].sudo().search([])

            filtered_ids = [p.id for p in products if re.search(pattern, p.name.lower())]

            domain = [('id', 'in', filtered_ids)] if filtered_ids else [('id', '=', 0)]

            _logger.info("Whole-word search applied for '%s' -> %s", search, filtered_ids)

        return domain

* Add this controller to your custom module.

* Restart Odoo and upgrade the module.

* Search in /shop — now only exact word matches (e.g., “ram”) will appear.

Hope it helps

There is more to the /shop/... routes than is covered by your source - see also https://github.com/odoo/odoo/blob/19.0/addons/website_sale/controllers/main.py#L487.

What's most crucial to your scenario is the bins key.

A working source - but far from being optimized nor covering all aspects such as filters etc. - is:
