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