I am trying to write this query;

localhost/solr/tvrh/?q=queryString&version=2.2&indent=on&tv.tf_idf=true

using solrj.

I want to get tf and idf values below; 

<lst name="doc-40797">

Up to now;

        SolrQuery query = new SolrQuery(queryString);
        query.setQueryType("/tvrh");
        query.setParam("tv.tf_idf", true);
        QueryResponse response = server.query(query);

I have written the query and I think I am gonna need QueryResponse object, I think it is true. But I don't know what is next to get those tf-idf values using solrj.

Thanks

You were almost there:

QueryResponse qr = server.query(query);
TermsResponse resp = qr.getTermsResponse();

The TermsResponse object contains the term vector component output. Not sure if it contains all the information though.

  • first of all thank you for your answer. I thought nobody was gonna help me. Thank you again. I now can get tf and idf values by using solution of another stackoverflow question(http://goo.gl/FLWx0). But since results turns document by document(as it shown in the question) I can only get one document's tf idf values, how can I get all document's values? – yns Nov 02 '12 at 12:00
