• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu sang - thanh ((((trang tuan) OR (trong tuan))) OR (trung tuan)) duong cong san toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu sang - thanh ((((trang tuan) OR (trong tuan))) or (trung tuan)) duong cong san toan tap*".
