Perhaps you should try some spelling variations:
decrease faster » decrease after (Expand search), decrease further (Expand search), decreased after (Expand search)
faster decrease » rate decrease (Expand search)
the processing » the process (Expand search), image processing (Expand search)
pitoni python » pitons python (Expand search), piton python (Expand search), pythons python (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)
python api » python 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 faster decrease the processing ) OR ( python api pitoni python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease faster decrease the processing ) OR ( python api pitoni python programming ))*.
