• If you are trying to use Boolean operators, they must be ALL CAPS: ((doi chieu) OR (doc hieu)) xanh - hanh trinh cua dong ((cong van) OR (song van)) chat cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) OR (doc hieu)) xanh - hanh trinh cua dong ((cong van) or (song van)) chat cau~".
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) OR (doc hieu)) xanh - hanh trinh cua dong ((cong van) or (song van)) chat cau*.
