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