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