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

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 ("synchronised steering"))) or ("synchronized stemming"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("synchronised stemming") OR ("synchronised steering"))) OR ("synchronized stemming"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"synchronised stemming\") OR (\"synchronised steering\"))) or (\"synchronized stemming\"))*".
• Removing quotes may allow a broader search: (((( synchronised stemming ) OR ( synchronised steering ))) or ( synchronized stemming ))*.
