Perhaps you should try some spelling variations:
"synchronised streaming" » "synchronized streaming", "synchronism streaming", "synchronised treating"
"synchronising streaming" » "synchronising treating", "synchronizing streaming", "synchronism streaming", "synchronisations streaming"
"synchronize swimming" » "synchronized swimming", "synchronism 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 ("synchronising streaming"))) OR ("synchronize swimming"))~.
• Removing quotes may allow a broader search: (((( synchronised streaming ) or ( synchronising streaming ))) or ( synchronize swimming ))~.
• Adding a wildcard symbol may retrieve word variants: (((("synchronised streaming") or ("synchronising streaming"))) or ("synchronize swimming"))*.
