ElasticSearch查询_elasticsearch中 list

    最近遇到了一个叫ElasticSearch盆友，用它玩了一下查询游戏：

List<Map<String, Object>> dataList = new ArrayList<Map<String, Object>>();
Client client = null;
try{
    //获取Elasticsearch client对象
    client = getEsClient();
    //设置查询条件（类似sql中 eventid = eventid )
    QueryBuilder qb = QueryBuilders.boolQuery().must(QueryBuilders.termQuery("eventid", eventid));
    // 设置ES中 indexName 和 indexType，以及QueryBuilders 对象
    SearchRequestBuilder requestBuilder = client.prepareSearch(EventBean.indexName)
        .setTypes(EventBean.indexType)
        .setQuery(qb);
    //执行查询 （可以设置排序、分页）
    SearchResponse actionGet = requestBuilder.addSort(SortBuilders.fieldSort("occurtime").order(SortOrder.DESC))
        .setFrom((pageNum-1) * pageSize)
        .setSize(pageNum * pageSize)
        .execute().actionGet();
    //遍历查询结
