• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"nijhoff book title 2007\\") or (\\"nijhoff ((boston title) OR (button title)) 2007\\"))\"".
• Removing quotes may allow a broader search: (( nijhoff book title 2007 ) or ( nijhoff ((boston title) OR (button title)) 2007 )).
