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