"del paciente from heat" » "del paciente con heat", "del pacientes qom heat", "del science from heat", "del presente from heat", "del ambiente from heat"
"en seres from le" » "en scenes from le", "en laseres from le", "en saberes from le", "en serie from le", "en seres from her", "en seres 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: "((((\"en sciences hours ver\") OR (\"del paciente from heat\"))) OR (\"en seres from le\"))~".
• Removing quotes may allow a broader search: (((( en sciences hours ver ) OR ( del paciente from heat ))) OR ( en seres from le ))~.
• Adding a wildcard symbol may retrieve word variants: (((("en sciences hours ver") OR ("del paciente from heat"))) OR ("en seres from le"))*.
