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

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