We need to have a document id available for every document (Per core). There is DocID in Lucene Index but did not find any API to expose it using Solr.
May be if we can alter Solr to optionally return the DocId (which is unique), We can pass docid as one of the parameter for fq, and it will return the docid in the search result.
