Perhaps you should try some spelling variations:
pattern python » pattern action (Expand search), pattern method (Expand search)
based pattern » based battery (Expand search), based plasters (Expand search), mapped pattern (Expand search)
decrease not » decrease of (Expand search), decrease akt (Expand search), decrease at (Expand search)
not decrease » to decrease (Expand search), not increase (Expand search), and decrease (Expand search)
python based » action based (Expand search)
decrease it » decrease its (Expand search), decrease in (Expand search), decrease il (Expand search)
it process » point process (Expand search), audit process (Expand search), test process (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 NOT decrease it process ) OR ( python based pattern python programming ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease not decrease it process ) OR ( python based pattern python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease not decrease it process ) OR ( python based pattern python programming ))*.
