Invoking a SerachHandler inside Solr Plugin

[Max Bridgewater <ma...@gmail.com>]

I am looking for best practices when a search component in one handler,
needs to invoke another handler, say /basic. So far, I got this working
prototype:

public void process(ResponseBuilder rb) throws IOException {
          SolrQueryResponse response = new SolrQueryResponse();
         ModifiableSolrParams params=new ModifiableSolrParams();
         params.add("defType",
"lucene").add("fl","product_id").add("wt","json").
add("df","competitor_product_titles").add("echoParams","explicit").add("q",rb.req.getParams().get("q"));
              SolrQueryRequest request= new
LocalSolrQueryRequest(rb.req.getCore(),params );
              SolrRequestHandler hdlr =
rb.req.getCore().getRequestHandler("/basic");
              rb.req.getCore().execute(hdlr, request, response);
          DocList
docList=((ResultContext)response.getValues().get("response")).docs;
         //Do some crazy stuff with the result
    }


My concerns:

1) What is a clean way to read the /basic handler's default parameters
from solrconfig.xml and use them in LocalSolrQueryRequest().
2) Is there a better way to accomplish this task overall?


Thanks,
Max.
