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