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