• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hien anh) OR (hien hanh)) - thanh truong phat ((nhung cong) OR (dung cong)) san toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien anh) or (hien hanh)) - thanh truong phat ((nhung cong) OR (dung cong)) san toan tap*".
