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