• If you are trying to use Boolean operators, they must be ALL CAPS: hoi chu tinh - thanh ((tinh luan) OR (binh luan)) ((phuong hoang) OR (nhung chong)) manh toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoi chu tinh - thanh ((tinh luan) OR (binh luan)) ((phuong hoang) or (nhung chong)) manh toan ban".
