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