• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho hieu) OR (ho chieu)) lang - ((hanh trinh) OR (canh tranh)) va phuong thong va tuan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho hieu) or (ho chieu)) lang - ((hanh trinh) OR (canh tranh)) va phuong thong va tuan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho hieu) or (ho chieu)) lang - ((hanh trinh) OR (canh tranh)) va phuong thong va tuan cau*.
