I have the following search criteria:
I'm trying to query all products and return ONLY products with both options A and B selected for the custom attribute free_from.
Currently with the above search criteria, A and B for example, i get search results for products where EITHER A or B is assigned.
I only want to return results where BOTH A and B are selected.
Is this possible? I'm assuming i would need to tap into the internal logic for querying products. Or should i simply change the search query in some way?
