• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky ((nang ha) OR (nang hai)) hoi. hieu ve ((cac tuc) or (cac tac)) vay doanh van cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((nang ha) OR (nang hai)) hoi. hieu ve ((cac tuc) OR (cac tac)) vay doanh van cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((nang ha) OR (nang hai)) hoi. hieu ve ((cac tuc) or (cac tac)) vay doanh van cua triet*".
