• If you are trying to use Boolean operators, they must be ALL CAPS: ho hieu lang - thanh ((((tuong va) OR (luong va))) OR (dung va)) nhung phuong dan toan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho hieu lang - thanh ((((tuong va) OR (luong va))) or (dung va)) nhung phuong dan toan tap".
• Adding a wildcard symbol may retrieve word variants: ho hieu lang - thanh ((((tuong va) OR (luong va))) or (dung va)) nhung phuong dan toan tap*.
