Examples of org.apache.solr.request.SolrRequestHandler.handleRequest()

org.apache.solr.request.SolrRequestHandler.handleRequest()
Handles a query request, this method must be thread safe.
Information about the request may be obtained from req and response information may be set using rsp.
There are no mandatory actions that handleRequest must perform. An empty handleRequest implementation would fulfill all interface obligations.

    NamedList terms;
    handler = core.getRequestHandler("/terms");
    assertTrue("handler is null and it shouldn't be", handler != null);
    rsp = new SolrQueryResponse();
    rsp.add("responseHeader", new SimpleOrderedMap());
    handler.handleRequest(new LocalSolrQueryRequest(core, params), rsp);
    values = rsp.getValues();
    terms = (NamedList) ((NamedList) values.get("terms")).get("standardfilt");
    assertTrue("terms Size: " + terms.size() + " is not: " + 3, terms.size() == 3);
    assertTrue("Item 0 name is not 'snake'", terms.getName(0).equals("snake"));
    assertTrue("Item 0 frequency is not '3'", (Integer) terms.getVal(0) == 3);
