• Performing a fuzzy search may retrieve terms with similar spellings: ((su sac) OR (su xac)) ky sang tai hai. hieu ve ((cam luc) or (cam xuc)) va doan vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su xac)) ky sang tai hai. hieu ve ((cam luc) OR (cam xuc)) va doan vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) OR (su xac)) ky sang tai hai. hieu ve ((cam luc) or (cam xuc)) va doan vi cua te".
• Adding a wildcard symbol may retrieve word variants: ((su sac) OR (su xac)) ky sang tai hai. hieu ve ((cam luc) or (cam xuc)) va doan vi cua te*.
