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