Perhaps you should try some spelling variations:
hidden processes » hidden properties (Expand search), written processes (Expand search), driven processes (Expand search)
decreased speed » decreased sleep (Expand search), decreased sperm (Expand search), decreased need (Expand search)
decrease hidden » decrease burden (Expand search), decrease violent (Expand search)
speed decrease » stent decrease (Expand search)
methods python » methods action (Expand search), pythons python (Expand search), methods 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: "(( decreased speed decrease hidden processes ) OR ( python AND methods python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decreased speed decrease hidden processes ) OR ( python AND methods python programming ))*.
