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

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