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