Perhaps you should try some spelling variations:
"big ofthe conference" » "big oate conference", "big atthe conference", "big fifth conference", "big often conference"
"big other conference" » "big other convergence", "big other inference", "big southern conference", "wig other conference", "big brother conference", "being other conference"
"being open conference" » "being european conference", "being europe conference", "being asian conference", "breaking open conference"

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: (("being open conference") OR ((("big ofthe conference") OR ("big other conference")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"being open conference\") or (((\"big ofthe conference\") OR (\"big other conference\"))))".
• Removing quotes may allow a broader search: (( being open conference ) or ((( big ofthe conference ) OR ( big other conference )))).
• Adding a wildcard symbol may retrieve word variants: (("being open conference") or ((("big ofthe conference") OR ("big other conference"))))*.
