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