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

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("synchronized stemming") or ("synchronism stemming"))) or ((("synchronize steering") or ("synchronize streaming"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("synchronized stemming") OR ("synchronism stemming"))) OR ((("synchronize steering") OR ("synchronize streaming")))).
• Removing quotes may allow a broader search: (((( synchronized stemming ) or ( synchronism stemming ))) or ((( synchronize steering ) or ( synchronize streaming )))).
• Adding a wildcard symbol may retrieve word variants: (((("synchronized stemming") or ("synchronism stemming"))) or ((("synchronize steering") or ("synchronize streaming"))))*.
