• The words AND, OR and NOT may confuse the search; try adding quotes: "(( eso astrophysics symposia, european ((youth observatory) OR (bath observatory)) ) or ((( eso astrophysics symposia, european county observatory ) or ( eso astrophysics symposia, european code observatory ))))".
• Adding a wildcard symbol may retrieve word variants: (( eso astrophysics symposia, european ((youth observatory) OR (bath observatory)) ) or ((( eso astrophysics symposia, european county observatory ) or ( eso astrophysics symposia, european code observatory ))))*.
