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