Perhaps you should try some spelling variations:
decrease disease » decreases disease (Expand search), increase disease (Expand search), increased disease (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
and decrease » and decreases (Expand search), and decreased (Expand search), and increase (Expand search)
action based » reaction based (Expand search), function based (Expand search)
under python » and python (Expand search), under path (Expand search)
based under » bases under (Expand search), base under (Expand search), raised under (Expand search)

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease AND decrease disease process ) OR ( action based under python programming ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease and decrease disease process ) OR ( action based under python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease and decrease disease process ) OR ( action based under python programming ))*.
