Perhaps you should try some spelling variations:
"proceedings 3rd report" » "proceedings 2nd report", "proceedings 13th report", "proceedings _ report", "proceedings word report", "proceedings cad report"
"proceedings el report" » "proceedings ec report", "proceedings etc report", "proceedings 2 report", "proceedings rl report", "proceedings evil report", "proceedings all report"
"proceedings ed report" » "proceedings ec report", "proceedings 2nd report", "proceedings etc report", "proceedings d report", "proceedings oecd report", "proceedings need report"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("proceedings el report") OR ((("proceedings ed report") OR ("proceedings 3rd report")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"proceedings el report\") or (((\"proceedings ed report\") OR (\"proceedings 3rd report\"))))".
• Removing quotes may allow a broader search: (( proceedings el report ) or ((( proceedings ed report ) OR ( proceedings 3rd report )))).
• Adding a wildcard symbol may retrieve word variants: (("proceedings el report") or ((("proceedings ed report") OR ("proceedings 3rd report"))))*.
