Perhaps you should try some spelling variations:
paciente food » paciente con
paciente book » paciente con
del paciente » de pacientes, del docente, del presente
science food » science mad, science vol
ever\" » ver\", over\", even\"
every\" » very\", overy\", eveny\"

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 food ever\\") OR (\\"del ((paciente book) OR (science food)) every\\"))\"".
• Removing quotes may allow a broader search: (( del paciente food ever ) OR ( del ((paciente book) OR (science food)) every )).
