You may search for a manufacturer (product line), company name or state.
The search will automatically respond with partial matches; e.g.,
entering "AME" in company will obtain "American".
If you use multiple parameters, and use the "or" command to join, the search will respond with
matches or partial matches to either entry. This is the broadest search, e.g. entering
VA for State and American for company will result all listings in Virginia or companies with a name
containing "American" (in or out of Virginia). If you use the "and" command to join
the same request will result only in companies named "American" within Virginia.
