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