• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sang - canh ((tranh ha) OR (trinh ha)) thong ((thong dan) OR (tuong dan)) van ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sang - canh ((tranh ha) or (trinh ha)) thong ((thong dan) OR (tuong dan)) van ban*".
