Perhaps you should try some spelling variations:
"synchronising stemming" » "synchronizing stemming", "synchronism stemming", "synchronisations stemming", "synchronising flemming", "synchronising stepping", "synchronising stealing"
"synchronising steering" » "synchronizing steering", "synchronism steering", "synchronisations steering"
"synchronize streaming" » "synchronized streaming", "synchronism streaming", "synchronizing streaming", "synchronize treating"

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 ("synchronising steering"))) or ("synchronize streaming"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("synchronising stemming") OR ("synchronising steering"))) OR ("synchronize streaming"))*.
• Removing quotes may allow a broader search: (((( synchronising stemming ) or ( synchronising steering ))) or ( synchronize streaming ))*.
