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