• Performing a fuzzy search may retrieve terms with similar spellings: ((so sach) OR (so sanh)) y trong van hoc. hieu ve cam cua ban thanh vai ((cua triet) or (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sach) OR (so sanh)) y trong van hoc. hieu ve cam cua ban thanh vai ((cua triet) OR (cua viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) OR (so sanh)) y trong van hoc. hieu ve cam cua ban thanh vai ((cua triet) or (cua viet))".
• Adding a wildcard symbol may retrieve word variants: ((so sach) OR (so sanh)) y trong van hoc. hieu ve cam cua ban thanh vai ((cua triet) or (cua viet))*.
