• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"dung tri quan van. hoi dong co mo\") OR (\"phung thi dua van. con duong uoc mo\"))~".
• Removing quotes may allow a broader search: (( dung tri quan van. hoi dong co mo ) OR ( phung thi dua van. con duong uoc mo ))~.
• Adding a wildcard symbol may retrieve word variants: (("dung tri quan van. hoi dong co mo") OR ("phung thi dua van. con duong uoc mo"))*.
