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