• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease at decreases disease process ) OR ( python script model period programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease at decreases disease process ) OR ( python script model period programming ))*.
