We have implemented custom storefront and using storefront API to list down the products. We needed to filter the products by 2 metafields, vendor name and the title. We followed method to filter the products.
But now the issue is in this approach we are unable to filter products by title. Because filter in a collection provides only following filters which doesn't include the title attribute.
Please write an example code to filter the products by title when the products are inside the collection.
