Now when searching products from a product list in Admin → Catalog → Products, you cannot find products by typing in product code.
For a seller a product code (if properly used) can be a short hand version of the description since a lot of information can be encoded into the product code.
It is a shame it does not search in product codes…
EDIT: There are other ways to search for a model number through other fields, like on the bottom or through advanced search. However, it would be cool if the first search box would also search model numbers.
I can search by product code in admin so I am not sure if you are referring to the product listing as the search by product code is at the bottom under “or choose” or if you are referring to some other area?
