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