Perhaps you should try some spelling variations:
"vassil" » "vassilis"
"vasil" » "vasile", "vasily", "basil"
"vasiley" » "vasileey", "vasilyey", "basiley", "vasile", "vasily", "vasiliy"
"vasilev" » "vasileev", "vasilyev", "basilev", "vasiliev", "vasile"
"vassall" » "vassals", "hassall"

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: (("vassil" OR ("vasil" OR ("vasiley" OR "vasilev"))) OR "vassall").
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"vassil\" or (\"vasil\" or (\"vasiley\" OR \"vasilev\"))) or \"vassall\")".
• Removing quotes may allow a broader search: (( vassil or ( vasil or ( vasiley OR vasilev ))) or vassall ).
• Adding a wildcard symbol may retrieve word variants: (("vassil" or ("vasil" or ("vasiley" OR "vasilev"))) or "vassall")*.
