• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu xanh - ((hanh trinh) OR (thanh trung)) cua trong cong ban ((than cap) OR (thanh cac))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - ((hanh trinh) or (thanh trung)) cua trong cong ban ((than cap) OR (thanh cac))~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - ((hanh trinh) or (thanh trung)) cua trong cong ban ((than cap) OR (thanh cac))*.
