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

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

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