问CTSDB ${metric}/doc/_bulk 插入多条，只能查询到1条 为什么？

插入点

curl -u root:password -X POST ip:port/mapp/doc/_bulk -d '

{"index": {}}

{ "http_code": "200","count1":61,"count2":7}

{"index": {}}

{"http_code": "200","count1":65,"count2":27}

查询点

curl -u root:password -X GET ip:port/mapp/_search -d'

{

"query": {

},

"docvalue_fields":["http_code"]

}'

插入数据2条 查询时 只有一条
