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