• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"dong cac doan van.\") OR (\"dung cac dan van.\"))) OR (\"chong cac dan van.\"))~".
• Removing quotes may allow a broader search: (((( dong cac doan van. ) OR ( dung cac dan van. ))) OR ( chong cac dan van. ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dong cac doan van.") OR ("dung cac dan van."))) OR ("chong cac dan van."))*.
