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