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