-------------------------------------------------------------
The use case is the following:
* We get catalog data from vendors (300+). We have no control about the data.
* The only unique thing is the catalogid, which is of course the same for all
rows in one catalog.
* In our webapp we request first only a few fields that are needed for the
search result display.
* When the customer clicks on a product in the search result he gets a detailed
page. To get the info from Solr we need a unique id to read the rest of the
fields (50+). This id is generated by this code.
Of course we could add the unique id in a preprocessing step but we wanted to
achieve this with Solr alone.
The update procedure goes like this:
* Delete all documents with a specific catalogId
* Insert the updated catalog data
So you see we need this id to find the exact same document we have in the
search result. We do nothing more with it.
Maybe I overlooked something and this can be achieved with existing code. Any
hint is welcome.

So you see we need this id only for reference. We do nothing more with it.
