• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease OR decrease decrease processes ) OR ( python used methods co2 programming ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease or decrease decrease processes ) OR ( python used methods co2 programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease or decrease decrease processes ) OR ( python used methods co2 programming ))*.
