Search based on store & category description

I’m using Coupons RT, and I don’t generally give the store name in the title or description of the Coupons. The Search Box though seems to search only based on title and description. So if suppose someone searches “amazon” on my site, he/she doesn’t get a list of amazon coupons (even though they exist).

Would like to know how are others handling/avoiding this thing? Or is there no other way but to add the store’s name somewhere in coupon title or description?
