premtemp on "index PDF file with DSE"

Hello,
I have PDF documents with no predefine schema that I would like to index using datastax enterprise.

I would like to index the file with solr and save the file on the CFS/cassandra DB. Users can then query for some keyword and SOLR should return some snippet and link to the file.

What are the steps to do the above task using DSE/SOLR/Cassandra

Thanks for your help
