• If you are trying to use Boolean operators, they must be ALL CAPS: (produc OR ((producent OR productive) OR ((productstsed OR producedt) OR productser))).
• Adding a wildcard symbol may retrieve word variants: (produc or ((producent or productive) or ((productstsed or producedt) or productser)))*.
