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