If too many types match your search string you will notice the ellipsis mark at the list end. You then will have to refine your search criterion by appending more characters to the search string or perhaps removing the wildcard characters from it.
By default, only types from the solution are shown in the lookup list. To display types from the libraries, check the Include library types check box.
