• Performing a fuzzy search may retrieve terms with similar spellings: (("tu cach thoi trac nguoi") OR ((("tu hach toc tay nguoi") OR ("thu hinh hoc bang nguoi"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"tu cach thoi trac nguoi\") OR (((\"tu hach toc tay nguoi\") OR (\"thu hinh hoc bang nguoi\"))))*".
• Removing quotes may allow a broader search: (( tu cach thoi trac nguoi ) OR ((( tu hach toc tay nguoi ) OR ( thu hinh hoc bang nguoi ))))*.
