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