sql例子

创建索引库，demo 为 index, user 为 type, 8 以后会被弃用

PUT /demo/user/_bulk?refresh
{"index":{"_id": "1111111"}}
{"name": "name1", "author": "author1", "release_date": "2011-06-02", "page_count": 1}
{"index":{"_id": "2222222"}}
{"name": "name2", "author": "author2", "release_date": "1989-05-26", "page_count": 2}
{"index":{"_id": "3333333"}}
{"name": "name3", "author": "author3", "release_date": "1965-06-01", "page_count": 3}

查询

POST /_sql?format=txt
{
  "query": "select * from demo"
