• If you are trying to use Boolean operators, they must be ALL CAPS: (( medicina de ((cc peru) OR (coca peru)) luis m ; ) OR ( ediciones de ninos de robio pau ; ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( medicina de ((cc peru) OR (coca peru)) luis m ; ) or ( ediciones de ninos de robio pau ; ))~".
• Adding a wildcard symbol may retrieve word variants: (( medicina de ((cc peru) OR (coca peru)) luis m ; ) or ( ediciones de ninos de robio pau ; ))*.
