• Performing a fuzzy search may retrieve terms with similar spellings: (("tu sach hoi lam nguoi") OR ((("su sach hoi lam nguoi") OR ("su cach thoi lam nguoi"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"tu sach hoi lam nguoi\") OR (((\"su sach hoi lam nguoi\") OR (\"su cach thoi lam nguoi\"))))".
• Removing quotes may allow a broader search: (( tu sach hoi lam nguoi ) OR ((( su sach hoi lam nguoi ) OR ( su cach thoi lam nguoi )))).
• Adding a wildcard symbol may retrieve word variants: (("tu sach hoi lam nguoi") OR ((("su sach hoi lam nguoi") OR ("su cach thoi lam nguoi"))))*.
