Hi Aditya,
Thank you for your suggestion!
Unfortunately, this is not possible, as there is no common format for
all product keys. The products are not ours nor are they all from the
same manufacturer, so we don't have any influence on how the product
keys look like.
Regards,
Christoph

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.

Hello,
we use lucene as search engine in an online shop. The products in this
shop often contain product keys like CRXUSB2.0-16GB.
We would like our customers to be able to find products by entering their
key. The problem is that product keys sometimes contain spaces or dashes
and customers sometimes don't enter these whitespaces correctly. On the
other hand, some customers enter whitespaces where there are none. Is there
an analyzer or some other method that allows us to find the product if the
user enters things like:
- "CRX USB2.0 16GB"
- "CRXUSB2.016GB"
- "CRX USB-2.0 16GB"
...
The problem is that the product keys don't all have a common format and
are contained in the normal text, so we don't have an easy way to treat
them different to the rest of the text.
Any help would be great!
Best regards,
Christoph
