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

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