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)
decrease test » decreases pest (Expand search), decrease their (Expand search), decrease costs (Expand search)
based pattern » based battery (Expand search), based plasters (Expand search), mapped pattern (Expand search)
decrease can » decrease in (Expand search), decrease and (Expand search), decrease at (Expand search)
can decrease » and decrease (Expand search), can increase (Expand search), to decrease (Expand search)
test process » testing process (Expand search), it 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 can decrease test process ) OR ( function based pattern python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease can decrease test process ) OR ( function based pattern python programming ))*.
