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