Perhaps you should try some spelling variations:
del paciente » de pacientes, del docente, del presente
paciente vol » paciente con, pacientes con, science vol
science hors » sciences hors, science vol
paciente mad » paciente con, science mad
every » very, overy, eveny, edery
ever » over, even, eder

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: "(((( del paciente vol every ) OR ( open science hors ever ))) OR ( del paciente mad ver ))~".
• Adding a wildcard symbol may retrieve word variants: (((( del paciente vol every ) OR ( open science hors ever ))) OR ( del paciente mad ver ))*.
