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

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

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