• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"trinh dung lam va kiem soat\") OR (\"anh huong luan toan tien hoat\"))~".
• Removing quotes may allow a broader search: (( trinh dung lam va kiem soat ) OR ( anh huong luan toan tien hoat ))~.
• Adding a wildcard symbol may retrieve word variants: (("trinh dung lam va kiem soat") OR ("anh huong luan toan tien hoat"))*.
