I'm migrating a working module from ThirtyBees to Prestashop 1.7.6.8 - the purpose of the module is to display selected categories on Manufacturer pages. The problem is, I cannot seem to get the grasp of the new SearchQuery mechanism. It seems like a great upgrade but ....
I can specify 1 category by using: $query->setIdCategory($category_id); Query being of type ProductSearchQuery
Is there an example somewhere on how to combine Queries? (In the working module, I just do a id_category IN (2,4,6) for instance
