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