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