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