• If you are trying to use Boolean operators, they must be ALL CAPS: thu san ((kho tang) OR (cao tang)) ha noi. hieu vu cham luc van thanh ve ((cua te) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu san ((kho tang) OR (cao tang)) ha noi. hieu vu cham luc van thanh ve ((cua te) or (su triet))".
• Adding a wildcard symbol may retrieve word variants: thu san ((kho tang) OR (cao tang)) ha noi. hieu vu cham luc van thanh ve ((cua te) or (su triet))*.
