Perhaps you should try some spelling variations:
"synchronised swimming" » "synchronized swimming", "synchronism swimming", "synchronising swimming", "synchronised stemming"
"synchronised flemming" » "synchronized flemming", "synchronism flemming", "synchronising flemming", "synchronised fleming"
"synchronize flemming" » "synchronize fleming", "synchronized flemming", "synchronism flemming"
"synchronizing flemming" » "synchronizing fleming", "synchronized flemming"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("synchronised swimming") or ((("synchronised flemming") or ((("synchronize flemming") OR ("synchronizing flemming"))))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("synchronised swimming") OR ((("synchronised flemming") OR ((("synchronize flemming") OR ("synchronizing flemming")))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"synchronised swimming\") or (((\"synchronised flemming\") or (((\"synchronize flemming\") OR (\"synchronizing flemming\"))))))".
• Removing quotes may allow a broader search: (( synchronised swimming ) or ((( synchronised flemming ) or ((( synchronize flemming ) OR ( synchronizing flemming )))))).
• Adding a wildcard symbol may retrieve word variants: (("synchronised swimming") or ((("synchronised flemming") or ((("synchronize flemming") OR ("synchronizing flemming"))))))*.
