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