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

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