• Performing a fuzzy search may retrieve terms with similar spellings: so sach ly hang xa hoi. hieu ve cam tuc va tinh tai ((((cua tre) OR (cua triet))) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ly hang xa hoi. hieu ve cam tuc va tinh tai ((((cua tre) OR (cua triet))) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ly hang xa hoi. hieu ve cam tuc va tinh tai ((((cua tre) OR (cua triet))) or (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: so sach ly hang xa hoi. hieu ve cam tuc va tinh tai ((((cua tre) OR (cua triet))) or (cuu tre))*.
