• If you are trying to use Boolean operators, they must be ALL CAPS: (( astrophysics AND space sciences library ) OR ((((( astrophysics AND space sequences library ) OR ( astrophysics AND spaces sequences library ))) OR ( astrophysics AND space sequence library )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( astrophysics and space sciences library ) or ((((( astrophysics and space sequences library ) OR ( astrophysics and spaces sequences library ))) or ( astrophysics and space sequence library ))))".
• Adding a wildcard symbol may retrieve word variants: (( astrophysics and space sciences library ) or ((((( astrophysics and space sequences library ) OR ( astrophysics and spaces sequences library ))) or ( astrophysics and space sequence library ))))*.
