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