Perhaps you should try some spelling variations:
method python » method method (Expand search), python python (Expand search)
decrease akt » decrease at (Expand search), decrease and (Expand search), decrease after (Expand search)
akt decrease » and decrease (Expand search), not decrease (Expand search), any decrease (Expand search)
on processes » fenton processes (Expand search)
python based » action based (Expand search)
decrease on » decrease in (Expand search), decrease of (Expand search), decrease and (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 akt decrease on processes ) OR ( python based method python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease akt decrease on processes ) OR ( python based method python programming ))*.
