• Performing a fuzzy search may retrieve terms with similar spellings: co sac ky nang ((dai khoa) OR (tai khoa)). hieu ve cam luc ((va danh) or (va dinh)) day cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: co sac ky nang ((dai khoa) OR (tai khoa)). hieu ve cam luc ((va danh) OR (va dinh)) day cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "co sac ky nang ((dai khoa) OR (tai khoa)). hieu ve cam luc ((va danh) or (va dinh)) day cuu tre".
• Adding a wildcard symbol may retrieve word variants: co sac ky nang ((dai khoa) OR (tai khoa)). hieu ve cam luc ((va danh) or (va dinh)) day cuu tre*.
