• If you are trying to use Boolean operators, they must be ALL CAPS: (((produc OR produceert) OR (produced OR produce)) OR (producer OR (producent OR producert))).
• Adding a wildcard symbol may retrieve word variants: (((produc or produceert) or (produced or produce)) or (producer or (producent or producert)))*.
