Perhaps you should try some spelling variations:
"les sciences horst ver" » "les sciences hors ver", "en sciences horst ver", "life sciences horst ver", "del science horst ver"
"del presente con heat" » "el presente con heat", "y presente con heat", "del presente en heat", "del presente por heat", "del presente y heat"
"en saberes from le" » "en papers from le", "en scenes from le", "eds saberes from le", "de saberes from le", "y saberes from le", "en saberes from her", "en saberes from 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: "((((\"les sciences horst ver\") OR (\"del presente con heat\"))) OR (\"en saberes from le\"))~".
• Removing quotes may allow a broader search: (((( les sciences horst ver ) OR ( del presente con heat ))) OR ( en saberes from le ))~.
• Adding a wildcard symbol may retrieve word variants: (((("les sciences horst ver") OR ("del presente con heat"))) OR ("en saberes from le"))*.
