I want to expand the search function in website_sale to be able to search on a tag in the products_item.

Anyone who knows how to do it?

Here is my code:

You can see that I have added ('image_tags', 'ilike', srch), that I have created in another module.

class website_sale(website_sale):
    
    def _get_search_domain(self, search, category, attrib_values):
        domain = request.website.sale_product_domain()
        
        if search:
            for srch in search.split(" "):
                domain += [
                    '|', '|', '|', ('name', 'ilike', srch), ('description', 'ilike', srch),
                    ('description_sale', 'ilike', srch), ('product_variant_ids.default_code', 'ilike', srch),
                    ('image_tags', 'ilike', srch)]
        
        if category:
            domain += [('public_categ_ids', 'child_of', int(category))]
        
        if attrib_values:
            attrib = None
            ids = []
            for value in attrib_values:
                if not attrib:
                    attrib = value[0]
                    ids.append(value[1])
                elif value[0] == attrib:
                    ids.append(value[1])
                else:
                    domain += [('attribute_line_ids.value_ids', 'in', ids)]
                    attrib = value[0]
                    ids = [value[1]]
            if attrib:
                domain += [('attribute_line_ids.value_ids', 'in', ids)]

<template id="product_view_tags" inherit_id="website_sale.products_item">
            <xpath expr="//div[@itemprop='offers']" position="after">
                <t t-if="product.image_tags">
                    <t t-foreach="product.image_tags" t-as="tag">
                        <div class="text-info oe_subdescription" contenteditable="false">
                            <div itemprop="image_tags" t-field="tag.name"/>
                        </div>
                    </t>
                </t>
            </xpath>
</template>
