• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (mot chieu)) xanh - ((hanh trinh) OR (hanh chinh)) ve nhung phuong manh toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (mot chieu)) xanh - ((hanh trinh) OR (hanh chinh)) ve nhung phuong manh toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (mot chieu)) xanh - ((hanh trinh) OR (hanh chinh)) ve nhung phuong manh toan cau*.
