将传输客户端迁移到 RestHighLevelClient 搜索查询

如何解决将传输客户端迁移到 RestHighLevelClient 搜索查询

我是弹性搜索的新手。我必须将搜索查询从传输客户端迁移到 RestHighLevelClient。

以下是我需要迁移的传输客户端代码。

SearchRequestBuilder searchRequestBuilder = Client.prepareSearch(elasticsearchIndex);
    
            try {
                searchRequestBuilder.
                        setQuery(generateBoolQuery(keyword))
                        .setFrom(0).setSize(100).setExplain(true)
                        .execute().actionGet();
            } catch (Exception ex) {
                LOGGER.debug(errorMessage,ex);
                throw new BadKeywordFormatException("Keyword \'" + keyword + "\' has " + "Unsupported characters. ",ex);
            } 


I have written corresponding code as 

     SearchRequest searchRequest = new SearchRequest(elasticsearchIndex);
        SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
        searchSourceBuilder.query(generateBoolQuery(keyword));
        searchSourceBuilder.from(0).size(100).explain(true);
        searchRequest.source(searchSourceBuilder);
        SearchResponse searchResponse;
        try {
             searchResponse = elasticsearchClient.search(searchRequest,RequestOptions.DEFAULT);
        } catch (IOException e) {
            LOGGER.debug(errorMessage,e);
            throw new BadKeywordFormatException("Keyword \'" + keyword + "\' has " + "Unsupported characters. ",e);
        }

请告诉我这段代码有什么问题？请帮我正确对应的代码。

我正在附加执行此查询时收到的错误日志。
