• If you are trying to use Boolean operators, they must be ALL CAPS: ((produc OR productse) OR ((introduction OR (productives OR productivos)) OR (producent OR producers))).
• Adding a wildcard symbol may retrieve word variants: ((produc or productse) or ((introduction or (productives or productivos)) or (producent or producers)))*.
