Most scholarship search engines access a national database. Your best odds of winning are for local scholarships or those with very narrowly defined criteria. If using search engines that ask for your email address, you may want to set up a new email account to receive the many notifications that will be coming. Non-seniors can save time by using search engines that ask for your year in school or graduation year, or by reviewing local scholarships.
