• If you are trying to use Boolean operators, they must be ALL CAPS: ((((serie diarios) OR (serie dietarios))) OR (((sobre distintos) OR (sobre distintas)))).~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((serie diarios) or (serie dietarios))) or (((sobre distintos) OR (sobre distintas)))).~".
• Adding a wildcard symbol may retrieve word variants: ((((serie diarios) or (serie dietarios))) or (((sobre distintos) OR (sobre distintas)))).*.
