• Performing a fuzzy search may retrieve terms with similar spellings: ((so sanh) or (do sanh)) y nang ((cao hoi) OR (co hoi)). hieu va cam xuc ban thanh vi cua vat~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sanh) OR (do sanh)) y nang ((cao hoi) OR (co hoi)). hieu va cam xuc ban thanh vi cua vat.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sanh) or (do sanh)) y nang ((cao hoi) OR (co hoi)). hieu va cam xuc ban thanh vi cua vat".
• Adding a wildcard symbol may retrieve word variants: ((so sanh) or (do sanh)) y nang ((cao hoi) OR (co hoi)). hieu va cam xuc ban thanh vi cua vat*.
