• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease painting history decrease processes ) OR ( python code api python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease painting history decrease processes ) OR ( python code api python programming ))*.
