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