• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease co2 decreases th2 processes ) OR ( action using python 2a processing ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease co2 decreases th2 processes ) OR ( action using python 2a processing ))*.
