Please help with category search for store items

I downloaded and changed the category on all of my products to Miniatures/Furniture. I uploaded the file and all went well. However, when I search in the Miniatures/Furniture/1:12th Scale, my items are not included in the results. I have not been able to locate anyplace in the item description or selling pages to assign a scale, so how does the search work for other items? Why aren't mine showing up? It's hard to sell if no one can find your products.

I have a hard time finding my items as well. The search function doesn't find some of my items even with the full name in the search bar.
