• If you are trying to use Boolean operators, they must be ALL CAPS: (( condicion de campus poder la pau ; ) OR ( mediciones ((un campus) OR (un campo)) fe en paz ; ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( condicion de campus poder la pau ; ) or ( mediciones ((un campus) OR (un campo)) fe en paz ; ))~".
• Adding a wildcard symbol may retrieve word variants: (( condicion de campus poder la pau ; ) or ( mediciones ((un campus) OR (un campo)) fe en paz ; ))*.
