es按时间范围查询查不到数据

做了个简单的测试
入库：
PUT /jtthink/ipaddr/11
{
"name":"zhangfei",
"age":33,
"birth":"2017-10-08 23:15:18"
}
java客户端的查询
QueryBuilder qb = rangeQuery("birth")
.from("2017-10-1 10:10:10").to("2017-12-30 23:15:18");

    SearchResponse sr = client.prepareSearch("jtthink")
            .setTypes("ipaddr").setQuery(qb).get();

但是查不到数据，想问下问题出在哪里
