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