• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sang - thanh trung va thong ((((vuong dan) OR (tuong dan))) OR (huong dan)) ca tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sang - thanh trung va thong ((((vuong dan) OR (tuong dan))) or (huong dan)) ca tap*".
