• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu sang - thanh truong va khong ((cang san) OR (nang sang)) ((chan cau) OR (can cau)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu sang - thanh truong va khong ((cang san) OR (nang sang)) ((chan cau) or (can cau))".
