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