• If you are trying to use Boolean operators, they must be ALL CAPS: (( medicion de etica perez alan p ; ) OR ( mediciones de ((tanto de) OR (canto de)) loa pau ; ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( medicion de etica perez alan p ; ) or ( mediciones de ((tanto de) OR (canto de)) loa pau ; ))~".
• Adding a wildcard symbol may retrieve word variants: (( medicion de etica perez alan p ; ) or ( mediciones de ((tanto de) OR (canto de)) loa pau ; ))*.
