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