Perhaps you should try some spelling variations:
"en science book ever" » "en science food ever", "en science from ever", "en science vol ever", "open science book ever", "del science book ever", "new science book ever"
"en sciences hors new" » "les sciences hors new", "open science hors new", "open sciences hors new", "del sciences hors new", "new sciences hors new", "en sciences more new"
"_ sciences hors new" » "_ science hors new", "les sciences hors new", "_ sciences more new"

You may be able to get more results by adjusting your search query.

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