• Performing a fuzzy search may retrieve terms with similar spellings: thuy san ((ky sang) or (ky nang)) lai roi. hieu su chao xu va ((danh vi) OR (dinh vi)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuy san ((ky sang) OR (ky nang)) lai roi. hieu su chao xu va ((danh vi) OR (dinh vi)) cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuy san ((ky sang) or (ky nang)) lai roi. hieu su chao xu va ((danh vi) OR (dinh vi)) cua te*".
