簡單總結：

• 如果服務端是5.6以下的，選擇相同版本的TransportClient，避免一些API服務端不支持
• 如果服務端是5.6以上的，選擇相同版本的RestClient

TransportClient起步：

5.6及之前的版本：?

// on startup Client client = TransportClient.builder().build().addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("host1"), 9300)).addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("host2"), 9300));// on shutdown client.close();

6.0及之后的版本：

// on startupTransportClient client = new PreBuiltTransportClient(Settings.EMPTY).addTransportAddress(new TransportAddress(InetAddress.getByName("host1"), 9300)).addTransportAddress(new TransportAddress(InetAddress.getByName("host2"), 9300));// on shutdownclient.close();

TransportClient發送搜索請求：

SearchResponse response = client.prepareSearch("index1", "index2").setTypes("type1", "type2").setSearchType(SearchType.DFS_QUERY_THEN_FETCH).setQuery(QueryBuilders.termQuery("multi", "test")) // Query.setPostFilter(QueryBuilders.rangeQuery("age").from(12).to(18)) // Filter.setFrom(0).setSize(60).setExplain(true).get();

HttpClient起步：

// Java Low Level REST Client RestClient lowLevelRestClient = RestClient.builder(new HttpHost("localhost", 9200, "http"),new HttpHost("localhost", 9201, "http")).build();// Java High Level REST Client RestHighLevelClient client = new RestHighLevelClient(lowLevelRestClient);

HttpClient發送搜索請求：

SearchRequest searchRequest = new SearchRequest(); searchRequest.source(sourceBuilder); SearchResponse searchResponse = client.search(searchRequest);
