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