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