二, java客户端调用Elasticsearch集群
1, 精准查询
2, 模糊查询(使用分词)
public class ESQueryClient {
    static Client CLIENT = null;
    static {
        // on startup
        Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name", "elasticsearch_useraudit").put("client.transport.sniff", true)
                .build();
        CLIENT = new TransportClient(settings).addTransportAddress(new InetSocketTransportAddress("127.0.0.1", 9301))
                .addTransportAddress(new InetSocketTransportAddress("127.0.0.1", 9302))
                .addTransportAddress(new InetSocketTransportAddress("127.0.0.1", 9303));
    }

    public static void main(String[] args) throws ElasticsearchException, IOException {
        // 通过id查询
        qryById();
        // 通过某个字段查询,例如uid, country
        SearchRequestBuilder builder = CLIENT.prepareSearch("useraudit").setTypes("t_participle_test").setSearchType(SearchType.DEFAULT)
                .setFrom(0).setSize(100);
        BoolQueryBuilder qb = QueryBuilders.boolQuery().must(new QueryStringQueryBuilder("眉山市").field("city"));
        builder.setQuery(qb);
        SearchResponse response = builder.execute().actionGet();
        System.out.println("字段为strin类型, mappin中未定义取消分词,精确查询不到数据, 测试结果:");
        System.out.println("通过city字段查询:" + response);
        System.out.println("通过city字段查询信息数量:" + response.getHits().getTotalHits());

        // 通过某个字段查询,例如uid, country
        builder = CLIENT.prepareSearch("useraudit").setTypes("t_participle_index_test").setSearchType(SearchType.DEFAULT).setFrom(0).setSize(100);
        qb = QueryBuilders.boolQuery().must(new QueryStringQueryBuilder("眉山市").field("city"));
        builder.setQuery(qb);
        response = builder.execute().actionGet();
        System.out.println("字段为strin类型, mappin中定义取消分词,精确查询数据 , 测试结果:");
        System.out.println("通过city字段查询:" + response);
        System.out.println("通过city字段查询信息数量:" + response.getHits().getTotalHits());

        // .should(new QueryStringQueryBuilder("太多").field("city"))
        CLIENT.close();
    }

    private static void qryById() {
        GetResponse response = CLIENT.prepareGet("useraudit", "t_participle_test", "1").setOperationThreaded(false).execute().actionGet();
        System.out.println("通过id查询:" + response.getSourceAsString());
    }
}

三, 索引数据的维护
四, 批量插入数据
测试数据量5千万
五, 压力测试并发精准查询和模糊查询
