• If you are trying to use Boolean operators, they must be ALL CAPS: ((viable OR ((vialle OR vitale) OR equivale)) OR (((vita OR vista) OR vital) OR vistal)).*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((viable or ((vialle or vitale) or equivale)) or (((vita OR vista) or vital) or vistal)).*".
