• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (chinh sach)) - thanh thuong ((thuat thong) OR (thuat trong)) cong dan than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (chinh sach)) - thanh thuong ((thuat thong) OR (thuat trong)) cong dan than cau".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) or (chinh sach)) - thanh thuong ((thuat thong) OR (thuat trong)) cong dan than cau*.
