Perhaps you should try some spelling variations:
"synchronised stepping" » "synchronism stepping", "synchronize stepping", "synchronising stepping", "synchronised stopping", "synchronised shopping", "synchronised shipping"
"synchronised streaming" » "synchronism streaming", "synchronize streaming", "synchronising streaming", "synchronised treating"
"synchronized stepping" » "synchronized stopping", "synchronized shopping", "synchronized shipping"

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

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