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