• Performing a fuzzy search may retrieve terms with similar spellings: (("ve cach thuc toc nguoi") or ((("tu sach nguoi tay nguoi") OR ("thu sach nguoi tay nguoi"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("ve cach thuc toc nguoi") OR ((("tu sach nguoi tay nguoi") OR ("thu sach nguoi tay nguoi")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"ve cach thuc toc nguoi\") or (((\"tu sach nguoi tay nguoi\") OR (\"thu sach nguoi tay nguoi\"))))".
• Removing quotes may allow a broader search: (( ve cach thuc toc nguoi ) or ((( tu sach nguoi tay nguoi ) OR ( thu sach nguoi tay nguoi )))).
