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