• Performing a fuzzy search may retrieve terms with similar spellings: ((((tu cach) OR (tu cac))) or (te sach)) ky nang x hoi. hieu ve cam duc va danh hu cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((tu cach) OR (tu cac))) OR (te sach)) ky nang x hoi. hieu ve cam duc va danh hu cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((tu cach) OR (tu cac))) or (te sach)) ky nang x hoi. hieu ve cam duc va danh hu cua tre".
• Adding a wildcard symbol may retrieve word variants: ((((tu cach) OR (tu cac))) or (te sach)) ky nang x hoi. hieu ve cam duc va danh hu cua tre*.
