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