Perhaps you should try some spelling variations:
variable » variables
vitalle » evitable, vistalle, vialle, vidalle
vitale » vitales, vitae, vistale, viale, vidale
vidale » vidales, vidal, vidala
revisable » previsible
vita » vista, via, vida
vital » vistal, vial, vidal
vistal » vista, vistas, nistal

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