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