• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho trieu) OR (30 trieu)) tinh - hanh trang cua ((nhung duong) OR (ung dung)) manh toan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho trieu) OR (30 trieu)) tinh - hanh trang cua ((nhung duong) or (ung dung)) manh toan tap".
• Adding a wildcard symbol may retrieve word variants: ((ho trieu) OR (30 trieu)) tinh - hanh trang cua ((nhung duong) or (ung dung)) manh toan tap*.
