Question

我正在运行我的第一个弹性搜索测试用例，我使用Java作为解决方案视角来进行弹性搜索实验。它在eclipse调试模式下完美运行，

调试模式结果：

{postDate=2016-01-31T10:32:58.952Z, title=Posting, content=today's weather is hot, tags=[hashtag]}

但是当我在正常运行应用程序模式下尝试此操作时，我收到以下异常，我根本不知道。请指导我。

以下例外：

8253 [main] INFO  org.elasticsearch.node  - [Marc Spector] started

我认为显示源代码可以更明确地解决问题

来源：

Node node = nodeBuilder().clusterName("testing2").node(); 
        Client client = node.client();

SearchResponse response = client.prepareSearch("facebook")
                .setTypes("Lance")
                .setSearchType(SearchType.QUERY_THEN_FETCH)
                .setQuery(QueryBuilders.matchPhrasePrefixQuery("title", "Pos"))
                .setFrom(0).setSize(60).setExplain(true)
                .execute()
                .actionGet();

        SearchHit[] searchResponse = response.getHits().getHits();

        for(SearchHit hit : searchResponse){
            System.out.println(hit.getSource());
        }

在查询你的facebook索引之前，你需要先创建它：

Settings indexSettings = ImmutableSettings.settingsBuilder()
                 .put("number_of_shards", 5)
                 .put("number_of_replicas", 1)
                 .build();
CreateIndexRequest indexRequest = new CreateIndexRequest("facebook", indexSettings);
client.admin().indices().create(indexRequest).actionGet();

如果您希望找到一些结果，您还需要索引数据：

IndexResponse response = client.prepareIndex("facebook", "Lance", "1")
        .setSource(jsonBuilder()
                    .startObject()
                        .field("title", "Posting")
                        .field("postDate", new Date())
                        .field("content", "today's weather is hot")
                        .field("tags", Lists.newArrayList("hashtag"))
                    .endObject()
                  )
        .execute()
        .actionGet();

然后你可以搜索索引。

希望这个帮助
