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