• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sac) OR (tu san)) ky nang ma hoa. hieu ve chat cua ban ((hang tri) or (hang tai)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu san)) ky nang ma hoa. hieu ve chat cua ban ((hang tri) OR (hang tai)) cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) OR (tu san)) ky nang ma hoa. hieu ve chat cua ban ((hang tri) or (hang tai)) cua te*".
