• If you are trying to use Boolean operators, they must be ALL CAPS: (( edicion del cambio de la pau ; ) OR ( medicina del campus de ((un par) OR (un pilar)) ; ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( edicion del cambio de la pau ; ) or ( medicina del campus de ((un par) OR (un pilar)) ; ))~".
• Adding a wildcard symbol may retrieve word variants: (( edicion del cambio de la pau ; ) or ( medicina del campus de ((un par) OR (un pilar)) ; ))*.
