• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"van hoa thoi ky van trong.\") OR (\"van hoa hoi ky dan trong.\"))~".
• Removing quotes may allow a broader search: (( van hoa thoi ky van trong. ) OR ( van hoa hoi ky dan trong. ))~.
• Adding a wildcard symbol may retrieve word variants: (("van hoa thoi ky van trong.") OR ("van hoa hoi ky dan trong."))*.
