Not able to read results of SuggestComponent using SolrJ API

Question

I am using SuggestComponent to get auto suggest keywords. I configured search component and request handler correctly in solrconfig.xml. I am getting expected results also.

Now my problem is i am not able to read XML output using SolrJ api. i spent couple of hours on SolrJ API, but not able to find method to read suggested keywords.

My Java Code

SolrServer server = //solrserver object creation
ModifiableSolrParams params = new ModifiableSolrParams();
params.set("qt", "/suggest");
params.set("q", q);
QueryResponse rsp = server.query(params);
**//How to read from QueryResponse?**

Here is my solrconfig.xml configuration

<searchComponent name="suggest" class="solr.SuggestComponent">
    <lst name="suggester">
      <str name="name">mySuggester</str>
      <str name="lookupImpl">AnalyzingInfixLookupFactory</str>      
      <str name="dictionaryImpl">DocumentDictionaryFactory</str>    
      <str name="field">name</str>
      <str name="weightField">reviewsNum</str>
      <str name="suggestAnalyzerFieldType">text_general</str>
      <str name="buildOnCommit">true</str>
    </lst>
  </searchComponent>

  <requestHandler name="/suggest" class="solr.SearchHandler" startup="lazy">
    <lst name="defaults">
      <str name="spellcheck">true</str>
      <str name="suggest">true</str>
      <str name="spellcheck.onlyMorePopular">true</str>
        <str name="suggest.count">10</str>
      <str name="suggest.dictionary">mySuggester</str>
    </lst>
    <arr name="components">
      <str>suggest</str>
    </arr>
  </requestHandler>

Response:

For temp fix, i am reading like this. List keywords = new ArrayList();NamedList — user475627, Dec 25 '14 at 05:33

You'll have to access the SpellCheckResponse property of the response:

rsp.getSpellCheckResponse()

This returns a SpellCheckResponse object, which contains the getSuggestions() method, which in turn returns a List of SpellCheckResponse.Suggestion objects.

List<SpellCheckResponse.Suggestion> suggestions = rsp.getSpellCheckResponse().getSuggestions()

You also want to use setRequestHandler("/suggest"), and not the qt parameter.

rsp.getSpellCheckResponse() is giving null. but rsp.getResponse() is giving data. – user475627 Dec 21 '14 at 09:58
MatsLindh,Here i am not using SpellCheckComponent class, rather i am using SuggestComponent class. So still response.getSpellCheckResponse() method will give results? – user475627 Dec 21 '14 at 12:04
