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