• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sach)) - thanh tung dat dung ((thong thanh) OR (rong thanh)) toan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sach)) - thanh tung dat dung ((thong thanh) or (rong thanh)) toan tap".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sach)) - thanh tung dat dung ((thong thanh) or (rong thanh)) toan tap*.
