• If you are trying to use Boolean operators, they must be ALL CAPS: ((((vital OR ((viral OR vial) OR vidal)) OR viales) OR ((vita OR vista) OR vida)) OR revistas).*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((vital or ((viral or vial) or vidal)) or viales) or ((vita OR vista) or vida)) or revistas).*".
