• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu xanh) OR (chieu sach)) - manh tung va dung ((cong ban) or (cong tan)) than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sach)) - manh tung va dung ((cong ban) OR (cong tan)) than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sach)) - manh tung va dung ((cong ban) or (cong tan)) than cau".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sach)) - manh tung va dung ((cong ban) or (cong tan)) than cau*.
