• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky nang xa hoi. hieu va tham luoc ((van anh) OR (van minh)) vi ((va triet) or (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. hieu va tham luoc ((van anh) OR (van minh)) vi ((va triet) OR (cua viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu va tham luoc ((van anh) OR (van minh)) vi ((va triet) or (cua viet))".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu va tham luoc ((van anh) OR (van minh)) vi ((va triet) or (cua viet))*.
