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