Perhaps you should try some spelling variations:
variable » variables
vitale » vitales, vitae, viale, vidale, vilale
evitable » evitables, inevitable, equitable, eviable, evidable, evilable
vitalle » vialle, vidalle, vilalle
vita » via, vida, vila
vital » vial, vidal, vilal
vista » visto
vistal » vistol, vistas, nistal, visbal

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: ((variable OR ((vitalle OR vitale) OR evitable)) OR (((vita OR vista) OR vital) OR vistal)).~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((variable or ((vitalle or vitale) or evitable)) or (((vita OR vista) or vital) or vistal)).~".
• Adding a wildcard symbol may retrieve word variants: ((variable or ((vitalle or vitale) or evitable)) or (((vita OR vista) or vital) or vistal)).*.
