Going off this, he would have to check the mini widget for every item that pops up, which might be a pain in the ass to store as it could change depending on how many items are filtered out using the search bar.
E.g.
User searches Feather
Results: [Feather] [blue Feather] [Red Feather]
Blue feathers widget might be 399, 11 for example, but if the user searches Blue Feather
The result would just be: [blue Feather] and the widget could change to 399, 10
