• Performing a fuzzy search may retrieve terms with similar spellings: doi ((chi xanh) or (chi hanh)) - thanh trung cua thong cong ((dan than) OR (van than)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chi xanh) OR (chi hanh)) - thanh trung cua thong cong ((dan than) OR (van than)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chi xanh) or (chi hanh)) - thanh trung cua thong cong ((dan than) OR (van than)) cau*".
