• If you are trying to use Boolean operators, they must be ALL CAPS: ((((peron OR perot) OR proud) OR (perol OR perol)) OR pero)({acute}actica OR {acute}practica) ;.
• Adding a wildcard symbol may retrieve word variants: ((((peron or perot) or proud) or (perol or perol)) or pero)({acute}actica or {acute}practica) ;*.
