• If you are trying to use Boolean operators, they must be ALL CAPS: (produc OR ((productser OR (producenten OR producten)) OR (producet OR ((producen OR producer) OR productsen))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(produc or ((productser or (producenten OR producten)) or (producet or ((producen or producer) or productsen))))*".
