• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu sach) OR (chieu sang)) - canh tranh tuan dung khang ((anh quan) OR (anh nhan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu sach) OR (chieu sang)) - canh tranh tuan dung khang ((anh quan) or (anh nhan)) cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu sach) OR (chieu sang)) - canh tranh tuan dung khang ((anh quan) or (anh nhan)) cau*.
