• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo chieu)) sang - hanh hang va ((thong duong) OR (thong dung)) van thanh ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (theo chieu)) sang - hanh hang va ((thong duong) or (thong dung)) van thanh ban*".
