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