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