• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"en science book ever\") OR (((\"del science hors new\") OR (\"new science vol new\"))))~".
• Removing quotes may allow a broader search: (( en science book ever ) OR ((( del science hors new ) OR ( new science vol new ))))~.
• Adding a wildcard symbol may retrieve word variants: (("en science book ever") OR ((("del science hors new") OR ("new science vol new"))))*.
