If you want a promotion to appear for a variety of highly similar queries, you can use regular expressions to define your trigger queries. For example:
pizza \d{5,5}will match any 5-digit postal code queries, like "pizza 98102"digital\scameras?will match the queries "digital camera" or "digital cameras".
