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