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