• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (theo tieu)) xanh - hanh trinh cua nhung ((dung dan) OR (dung san)) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (theo tieu)) xanh - hanh trinh cua nhung ((dung dan) OR (dung san)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (theo tieu)) xanh - hanh trinh cua nhung ((dung dan) OR (dung san)) toan ban*.
