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