Abstract: Methods and apparatus, including computer program products, are provided that include techniques for searching a database. One method includes receiving one or more input search terms and providing a database. The database maps at least one search term to at least one coupon. The method further includes identifying one or more coupons in the database based on the received input search terms. The method further includes selecting one or more coupons from the identified coupons. A given coupon can be selected based on a number of times the given coupon has been previously printed. A given coupon can also be selected based on a number of times the given coupon has been previously redeemed. The method further includes presenting one or more coupons to the user where the presented one or more coupons include the selected one or more coupons.
