• If you are trying to use Boolean operators, they must be ALL CAPS: (( medicion de campo juan ((flos pau) OR (las pau)) ; ) OR ( audicion y campos el local paz ; ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( medicion de campo juan ((flos pau) OR (las pau)) ; ) or ( audicion y campos el local paz ; ))~".
• Adding a wildcard symbol may retrieve word variants: (( medicion de campo juan ((flos pau) OR (las pau)) ; ) or ( audicion y campos el local paz ; ))*.
