Andrew:
I think Sam's original suggestion still makes sense. Not all fields are indexed and available on the "Find" button. For instance, if looking for all Customers in the city of Vancouver, a search using "Starts with" = "VAN" would get only Vancouver and not Estevan. Probably not the best example because there are other better ways to get that result. But adding "Starts with" would be a better tool in some cases to produce a shorter and possibly faster result list.
