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