ES使用AnalyzeRequest

验证ES分词情况，核心代码如下

 @Autowired
    private  RestHighLevelClient restHighLevelClient;
AnalyzeRequest analyzeRequest = AnalyzeRequest.withIndexAnalyzer(indexName,"ik_smart",text);
        AnalyzeResponse response = restHighLevelClient.indices().analyze(analyzeRequest, RequestOptions.DEFAULT);
        List<AnalyzeResponse.AnalyzeToken> tokens = response.getTokens();
        for (AnalyzeResponse.AnalyzeToken token : tokens) {
            String term = token.getTerm();
            System.out.println(term);
        }
