• Performing a fuzzy search may retrieve terms with similar spellings: ((te sac) or (te cac)) ky nang ((co hoi) OR (co loi)). thien van nam luoc van hanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sac) OR (te cac)) ky nang ((co hoi) OR (co loi)). thien van nam luoc van hanh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sac) or (te cac)) ky nang ((co hoi) OR (co loi)). thien van nam luoc van hanh vi cua triet".
• Adding a wildcard symbol may retrieve word variants: ((te sac) or (te cac)) ky nang ((co hoi) OR (co loi)). thien van nam luoc van hanh vi cua triet*.
