• If you are trying to use Boolean operators, they must be ALL CAPS: (((( rescue research service ) OR ((( rescue sar series ) OR ( rescue a series ))))) OR ( residue research theories )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( rescue research service ) or ((( rescue sar series ) OR ( rescue a series ))))) or ( residue research theories ))".
• Adding a wildcard symbol may retrieve word variants: (((( rescue research service ) or ((( rescue sar series ) OR ( rescue a series ))))) or ( residue research theories ))*.
