How to get Solr Unique Key while doing TermEnum

Hi,

In order to extract the Term Dictionary of the indexed document i am doing
this

IndexReader indexReader = IndexReader.open(indexDir);
	    terms = indexReader.terms(new Term("description_t", ""));
	    while (terms.next()){
		    if("description_t".equals(terms.term().field())){
		    	MultipleTermPositions mt=new MultipleTermPositions(indexReader,new
Term[]{terms.term()});
		    	while(mt.next()){
		    		System.out.println("Document Id="+mt.doc()+" for
term="+terms.term().text() + " Frequency "+mt.freq());
		    	}
		    }
	    }
This gives me the document id of lucene but i would like to get the Solr
Unique Id. Is there an api that would give me the id without loading the
entire document?

Thanks
Bharani

It takes a bit of memory, but you could use the FieldCache for this.
