coupon search

coupons are already searchable, if you have something other than that, please let me know complete thoughts so I could respond properly.

coupon is not searchable
there is not search box in your plugin
but in theme there is a search box , i m using wootique theme
but when i search something then its show only product or when i search show then its show coupon in post type not with coupon script
so is there any search box that i can search only coupon with its script and style dont lose
