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