Perhaps you should try some spelling variations:
variable » variables
vitalle » vitale, evitable, vistalle, vialle, vidalle
vidale » vidal, vidala
vidales » vidals, vidalas
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 (vidale OR vidales)) 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 (vidale OR vidales)) or revisable)) or ((vita or vital) or vistal)).~".
• Adding a wildcard symbol may retrieve word variants: ((variable or ((vitalle or (vidale OR vidales)) or revisable)) or ((vita or vital) or vistal)).*.
