Partial name shop search

So for some reason I can't search for items with only part of an item's name. I thought this was a quirk of the English patch. I know the Japanese version had some bad design choices but this is downright unprofessional.

For some reason you can only seem to search a specific name or through categories 😕 I'd love to be able to partial search, especially when I just want to look for all of certain items/sets.
