• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky nang xa hoi. chieu chien cac co va dinh vi ((((cua tre) OR (cua triet))) or (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang xa hoi. chieu chien cac co va dinh vi ((((cua tre) OR (cua triet))) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang xa hoi. chieu chien cac co va dinh vi ((((cua tre) OR (cua triet))) or (su triet))".
• Adding a wildcard symbol may retrieve word variants: su sach ky nang xa hoi. chieu chien cac co va dinh vi ((((cua tre) OR (cua triet))) or (su triet))*.
