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