• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ty nang x hoi. ((((chieu cao) OR (hieu ca))) or (hieu cac)) chat thuc va danh dai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty nang x hoi. ((((chieu cao) OR (hieu ca))) OR (hieu cac)) chat thuc va danh dai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty nang x hoi. ((((chieu cao) OR (hieu ca))) or (hieu cac)) chat thuc va danh dai cua tre".
• Adding a wildcard symbol may retrieve word variants: thu sach ty nang x hoi. ((((chieu cao) OR (hieu ca))) or (hieu cac)) chat thuc va danh dai cua tre*.
