Nope, there is not.

Hi,



I have a unique key within my index, but rather than the default
behavour of overwriting I am wondering if there is a method to "merge"
the two different documents on commit of the second document.  I have a
testcase which explains what I'd like to happen:



@Test

       public void testMerge() throws SolrServerException, IOException

       {

             SolrInputDocument doc1 = new SolrInputDocument();

             doc1.addField("secid", "testid");

             doc1.addField("value1_i", 1);



             SolrAllSec.GetSolrServer().add(doc1);

             SolrAllSec.GetSolrServer().commit();



             SolrInputDocument doc2 = new SolrInputDocument();

             doc2.addField("secid", "testid");

             doc2.addField("value2_i", 2);



             SolrAllSec.GetSolrServer().add(doc2);

             SolrAllSec.GetSolrServer().commit();



             SolrQuery solrQuery = new  SolrQuery();

             solrQuery = solrQuery.setQuery("secid:testid");

             QueryResponse response =
SolrAllSec.GetSolrServer().query(solrQuery, METHOD.GET);



             List<SolrDocument>  result = response.getResults();

             Assert.isTrue(result.size() == 1);

             Assert.isTrue(result.contains("value1"));

             Assert.isTrue(result.contains("value2"));

       }



Other than reading "doc1" and adding the fields from "doc2" and
recommitting, is there another way?



Thanks in advance,



Tim
