• Performing a fuzzy search may retrieve terms with similar spellings: toc sach v nang ((cao hoi) or (co hoi)). lieu va cham xuc ((van hanh) OR (ban hanh)) lai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach v nang ((cao hoi) OR (co hoi)). lieu va cham xuc ((van hanh) OR (ban hanh)) lai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach v nang ((cao hoi) or (co hoi)). lieu va cham xuc ((van hanh) OR (ban hanh)) lai cua triet".
• Adding a wildcard symbol may retrieve word variants: toc sach v nang ((cao hoi) or (co hoi)). lieu va cham xuc ((van hanh) OR (ban hanh)) lai cua triet*.
