Perhaps you should try some spelling variations:
"synchronised stemming" » "synchronism stemming", "synchronising stemming", "synchronised steering", "synchronised stealing", "synchronised stenning"
"synchronised stepping" » "synchronism stepping", "synchronising stepping", "synchronised stopping", "synchronised shopping", "synchronised shipping"
"synchronized stemming" » "synchronized steering", "synchronized stealing", "synchronized stenning", "synchronismd stemming", "synchronizingd stemming"
"synchronize flemming" » "synchronism flemming", "synchronizing flemming", "synchronize fleming"
"synchronize streaming" » "synchronism streaming", "synchronizing streaming", "synchronize treating"

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