• Performing a fuzzy search may retrieve terms with similar spellings: (("tu cach dao lam nguoi") or ((("thu sach bai dao nguoi") OR ("thu sach bai cho nguoi"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("tu cach dao lam nguoi") OR ((("thu sach bai dao nguoi") OR ("thu sach bai cho nguoi")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"tu cach dao lam nguoi\") or (((\"thu sach bai dao nguoi\") OR (\"thu sach bai cho nguoi\"))))".
• Removing quotes may allow a broader search: (( tu cach dao lam nguoi ) or ((( thu sach bai dao nguoi ) OR ( thu sach bai cho nguoi )))).
• Adding a wildcard symbol may retrieve word variants: (("tu cach dao lam nguoi") or ((("thu sach bai dao nguoi") OR ("thu sach bai cho nguoi"))))*.
