Query SolrIndex for Id

[Alaak]

Hi,

I have a problem with the way Nutch (1.6 trunk) stores the pages id to 
the Solr (3.6.1) index. It uses the pages URL. However due to special 
characters in the URL like ":" or "/" it is impossible to use the URL as 
query parameter to access documents on Solr. Of course it is possible to 
apply URL encoding, but it seems Solr does not invert the encoding on 
Server side and thus is unable to match the queried URL to the URL in 
the index. So does anyone know of a way to retrieve documents from a 
Nutch created Solr Index by id?

Thanks and Regards
