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