In order to find the most accurate search results, it maybe necessary to specify multiple search criteria. This means adding additional terms in the search box. For example, suppose a search for 'Yorke' returns too many results. You can additionally specify the registration number, first name, state, zip and license type to narrow the search results. In contrast, suppose a search for 'Yorke' returns no results. You can expand your search by including an asterisk 'York*'. Limiting the search phrase may increase your search results.
