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