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