@震秦 你好，想跟你请教个问题： 

<!-- mm suggest,, copyField is merge field a to dest=ab-->
	<searchComponent name="suggest" class="solr.SpellCheckComponent">
	  <str name="queryAnalyzerFieldType">textSpell</str> 
	  <lst name="spellchecker">

<!--mm suggest-->
	<requestHandler name="/suggest" class="solr.SearchHandler" startup="lazy">

solrj 调用 

HttpSolrServer solrServer =SolrServer.getInstance().getServer();
		solrServer.setRequestWriter(new BinaryRequestWriter()); 
		SolrQuery sQuery = new SolrQuery();
		ModifiableSolrParams params=new ModifiableSolrParams();
		params.set("qt", "/suggest");//spellhandler
		params.set("q",content);
		///CommonParams.QT 条件命名
		params.set("spellcheck", "on");  
        params.set("spellcheck.build", "true");  
		
        params.set("spellcheck.count", "10");  
        //params.set("spellcheck.alternativeTermCount", "4");  
       // params.set("spellcheck.onlyMorePopular", "false");
        
        //params.set("spellcheck.extendedResults", "false");  
       // params.set("spellcheck.maxResultsForSuggest", "5");  
  
        //params.set("spellcheck.collate", "true");  
       // params.set("spellcheck.collateExtendedResults", "true");  
        //params.set("spellcheck.maxCollationTries", "5");  
        //params.set("spellcheck.maxCollations", "3");
        
		sQuery.add(params);
		try {
			
			// 第一种方式 获得 entitylist 
			QueryResponse response = solrServer.query(sQuery);
			SpellCheckResponse spellCheckResponse = response.getSpellCheckResponse();
			if(spellCheckResponse != null){
				List<Suggestion> suggestionList=spellCheckResponse.getSuggestions();
				for(Suggestion suggestion:suggestionList){
					if(suggestion.getNumFound()!=0){
						List<String> suggestWordList=suggestion.getAlternatives();
						JsonMapper jsonMapper=JsonMapper.awalysMapper();
						String json = jsonMapper.toJson(suggestWordList);
						
						HttpServletResponse response1=ServletActionContext.getResponse();
						response1.setContentType("text/plain");
						response1.setCharacterEncoding("UTF-8");
						PrintWriter out=response1.getWriter();
						out.print(json);
						out.flush();
						out.close();
						break;
					}
				}
			}

List<Suggestion> suggestionList=spellCheckResponse.getSuggestions(); 没有任何 suggestion返回 。。

怎么办 ，求教

Answer 1

可以用这个方法,queryResponse.getSuggestion()
