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

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