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