• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease lesions disease covid processing ) OR ( decrease taping decrease AND decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions disease covid processing ) OR ( decrease taping decrease AND decrease ))*.
