Perhaps you should try some spelling variations:
decrease rate » decreased rate (Expand search), decreases rate (Expand search), decrease at (Expand search)
rate decrease » rats decreases (Expand search), ratio decrease (Expand search), rate increase (Expand search)
method python » method method (Expand search), python python (Expand search)
in processes » in process (Expand search), design processes (Expand search)
python api » python and (Expand search)
api method » iapi method (Expand search), bpi method (Expand search), epi method (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 rate decrease in processes ) OR ( python api method python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease rate decrease in processes ) OR ( python api method python programming ))*.
