• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"online rand search document\") or (((\"online hand research comments\") OR (\"online land research comments\"))))*".
• Removing quotes may allow a broader search: (( online rand search document ) or ((( online hand research comments ) OR ( online land research comments ))))*.
