• If you are trying to use Boolean operators, they must be ALL CAPS: (((("nijhoff book title 2009") OR ("nijhoff book title 20"))) OR ((("nijhoff op title 209") OR ((("nijhoff shup titles 2009") OR ("nijhoff issue titles 2009")))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"nijhoff book title 2009\") or (\"nijhoff book title 20\"))) or (((\"nijhoff op title 209\") or (((\"nijhoff shup titles 2009\") OR (\"nijhoff issue titles 2009\"))))))".
• Removing quotes may allow a broader search: (((( nijhoff book title 2009 ) or ( nijhoff book title 20 ))) or ((( nijhoff op title 209 ) or ((( nijhoff shup titles 2009 ) OR ( nijhoff issue titles 2009 )))))).
• Adding a wildcard symbol may retrieve word variants: (((("nijhoff book title 2009") or ("nijhoff book title 20"))) or ((("nijhoff op title 209") or ((("nijhoff shup titles 2009") OR ("nijhoff issue titles 2009"))))))*.
