• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"chuuong trinh hoi nhan.\") OR (((\"huong trinh do nhan.\") OR (\"cong trinh hoi nham.\"))))~".
• Removing quotes may allow a broader search: (( chuuong trinh hoi nhan. ) OR ((( huong trinh do nhan. ) OR ( cong trinh hoi nham. ))))~.
• Adding a wildcard symbol may retrieve word variants: (("chuuong trinh hoi nhan.") OR ((("huong trinh do nhan.") OR ("cong trinh hoi nham."))))*.
