Autofill 'id' field with the URL of files posted to Solr?

[Praveen Agrawal <pk...@gmail.com>]

Hi,
I need to submit thousands of online PDF/html files to Solr. I can submit
one file using SolrJ (StreamingUpdateSolrServer and
..solr.common.util.ContentStreamBase.URLStream), setting
literal.idparameter to the url. I can't do the same with a batch of
multiple files, as
their 'id' should be unique (set to their urls).

I couldn't get this to work. Is there a way to somehow get the 'id' field
set automatically to the url of the files posted to Solr (something like to
'stream_name')? How to set this in solrconfig.xml or schema.xml?  or any
other way?

Thanks.
