• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien anh - ((thanh thang) OR (thanh hang)) ((cua thuong) OR (cua truong)) thanh manh toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien anh - ((thanh thang) or (thanh hang)) ((cua thuong) OR (cua truong)) thanh manh toan tap~".
• Adding a wildcard symbol may retrieve word variants: hoc hien anh - ((thanh thang) or (thanh hang)) ((cua thuong) OR (cua truong)) thanh manh toan tap*.
