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