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