Perhaps you should try some spelling variations:
based processes » based process (Expand search), and processes (Expand search)
disease based » disease caused (Expand search), disease case (Expand search), diseases caused (Expand search)
python regius » python redes (Expand search)
regius piton » regis pinto (Expand search), regis piloni (Expand search), regius in (Expand search)
piton python » pitons python (Expand search), in python (Expand search), with python (Expand search)

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: "(( decrease AND disease based processes ) OR ( python regius piton python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease AND disease based processes ) OR ( python regius piton python programming ))*.
