• If you are trying to use Boolean operators, they must be ALL CAPS: (produc OR (((produce OR product) OR productte) OR (produzieren OR (produces OR productivity)))).
• Adding a wildcard symbol may retrieve word variants: (produc or (((produce or product) or productte) or (produzieren or (produces or productivity))))*.
