Hi Christoph My opinion is, you should not normalize or do any modification to the product keys. This should be unique. Should be used as it is. Instead of spaces you should have only used "-" but since the product already out in the market, it cannot help.
In your UI, You could provide multiple text box where user will fill respective chars. You could add space or "-" before passing the key to Lucene.
