Perhaps you should try some spelling variations:
nijhoff book » nijhoff boston, nijhoff op
book title » book titles, ebook title, book table
title 2006 » title 26, title 20, title 2012
op titles » up titles, comp titles, _ titles

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( nijhoff book title 2006 ) OR ( nijhoff ((op titles) OR (job titles)) 2006 )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( nijhoff book title 2006 ) or ( nijhoff ((op titles) OR (job titles)) 2006 ))".
• Adding a wildcard symbol may retrieve word variants: (( nijhoff book title 2006 ) or ( nijhoff ((op titles) OR (job titles)) 2006 ))*.
