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