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