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