• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (chieu tinh)) - thanh trung ((phap thong) OR (pho thong)) cong san than cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (chieu tinh)) - thanh trung ((phap thong) OR (pho thong)) cong san than cau*".
