Hi,

In odoo 17 you can check addons code

website_sale/models/product_template.py

check this method 

def _search_get_detail

@api.model
def _search_get_detail(self, website, order, options):
    with_image = options['displayImage']
    # with_description = options['displayDescription']
    with_category = options['displayExtraLink']
    with_price = options['displayDetail']
    domains = [website.sale_product_domain()]
    category = options.get('category')
    tags = options.get('tags')
    min_price = options.get('min_price')
    max_price = options.get('max_price')
    attrib_values = options.get('attrib_values')
    if category:
        domains.append([('public_categ_ids', 'child_of', unslug(category)[1])])
    if tags:
        if isinstance(tags, str):
            tags = tags.split(',')
        domains.append([('product_variant_ids.all_product_tag_ids', 'in', tags)])
    if min_price:
        domains.append([('list_price', '>=', min_price)])
    if max_price:
        domains.append([('list_price', '<=', max_price)])
    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:
                domains.append([('attribute_line_ids.value_ids', 'in', ids)])
                attrib = value[0]
                ids = [value[1]]
        if attrib:
            domains.append([('attribute_line_ids.value_ids', 'in', ids)])
    search_fields = ['name', 'default_code', 'product_variant_ids.default_code']
    fetch_fields = ['id', 'name', 'website_url']
    mapping = {
        'name': {'name': 'name', 'type': 'text', 'match': True},
        'default_code': {'name': 'default_code', 'type': 'text', 'match': True},
        'product_variant_ids.default_code': {'name': 'product_variant_ids.default_code', 'type': 'text', 'match': True},
        'website_url': {'name': 'website_url', 'type': 'text', 'truncate': False},
    }
    if with_image:
        mapping['image_url'] = {'name': 'image_url', 'type': 'html'}
    # if with_description:
    #     # Internal note is not part of the rendering.
    #     search_fields.append('description')
    #     fetch_fields.append('description')
    #     search_fields.append('description_sale')
    #     fetch_fields.append('description_sale')
    #     mapping['description'] = {'name': 'description_sale', 'type': 'text', 'match': True}
    if with_price:
        mapping['detail'] = {'name': 'price', 'type': 'html', 'display_currency': options['display_currency']}
        mapping['detail_strike'] = {'name': 'list_price', 'type': 'html', 'display_currency': options['display_currency']}
    if with_category:
        mapping['extra_link'] = {'name': 'category', 'type': 'html'}
    return {
        'model': 'product.template',
        'base_domain': domains,
        'search_fields': search_fields,
        'fetch_fields': fetch_fields,
        'mapping': mapping,
        'icon': 'fa-shopping-cart',
    }

Comment out 

with_description = options['displayDescription']

condition code and check then override this method in your custom module.

Thanks.
