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