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