• If you are trying to use Boolean operators, they must be ALL CAPS: (("nijhoff op title 2") OR ((("nijhoff sop title a") OR ("nijhoff ship title a")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"nijhoff op title 2\") or (((\"nijhoff sop title a\") OR (\"nijhoff ship title a\"))))".
• Removing quotes may allow a broader search: (( nijhoff op title 2 ) or ((( nijhoff sop title a ) OR ( nijhoff ship title a )))).
• Adding a wildcard symbol may retrieve word variants: (("nijhoff op title 2") or ((("nijhoff sop title a") OR ("nijhoff ship title a"))))*.
