Perhaps you should try some spelling variations:
pattern python » pattern action (Expand search), pattern method (Expand search)
function based » reaction based (Expand search), action based (Expand search), reflection based (Expand search)
based pattern » based battery (Expand search), based plasters (Expand search), mapped pattern (Expand search)
decrease of » decrease in (Expand search)
of decrease » or decrease (Expand search), not decrease (Expand search), to decrease (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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease of decrease it process ) OR ( function based pattern python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease of decrease it process ) OR ( function based pattern python programming ))*.
