• Performing a fuzzy search may retrieve terms with similar spellings: (("thanh nguoi khoa luan") or ((("tang nguoi kho luan") OR ("tang nguoi khau luan"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("thanh nguoi khoa luan") OR ((("tang nguoi kho luan") OR ("tang nguoi khau luan")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"thanh nguoi khoa luan\") or (((\"tang nguoi kho luan\") OR (\"tang nguoi khau luan\"))))".
• Removing quotes may allow a broader search: (( thanh nguoi khoa luan ) or ((( tang nguoi kho luan ) OR ( tang nguoi khau luan )))).
• Adding a wildcard symbol may retrieve word variants: (("thanh nguoi khoa luan") or ((("tang nguoi kho luan") OR ("tang nguoi khau luan"))))*.
