• If you are trying to use Boolean operators, they must be ALL CAPS: (((perod OR perof) OR (perofunda OR perofundo)) OR ((pro OR prof) OR pero)){acute}activa ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((perod or perof) or (perofunda or perofundo)) or ((pro OR prof) or pero)){acute}activa ;".
• Adding a wildcard symbol may retrieve word variants: (((perod or perof) or (perofunda or perofundo)) or ((pro OR prof) or pero)){acute}activa ;*.
