Distributed search using solrj?

Assuming your shards are:

"localhost: 8983 / solr" and "localhost: 7574 / solr"

You can do distributed searches with solrj, for example:

String shards = "localhost:8983/solr,localhost:7574/solr";
StringBuffer request = new StringBuffer();
request.append("&q=" + query);
request.append("&shards=" + shards);
SolrParams solrParams = SolrRequestParsers.parseQueryString(request
                .toString());
QueryResponse rsp = server.query(solrParams);

      

        
        
        
      

    

alternatively, you can use the ModifiableSolrParams class:

String shards = "localhost:8983/solr,localhost:7574/solr";
ModifiableSolrParams solrParams = new ModifiableSolrParams();
solrParams.set("q", query);
solrParams.set("shards", shards);
QueryResponse rsp = server.query(solrParams);
