Perhaps you should try some spelling variations:
"synchronised streaming" » "synchronized streaming", "synchronising streaming"
"synchronism streaming" » "synchronising streaming", "synchronized streaming"
"synchronism treating" » "synchronising treating", "synchronized treating", "synchronism creating", "synchronism heating", "synchronism relating"
"synchronize swimming" » "synchronized swimming", "synchronizing swimming", "synchronize stemming"

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

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