elasticsearch存入数据嵌入式数据解决扁平化查询问题

        嵌套查询搜索嵌套的字段对象，就像它们作为单独的文档被索引一样。如果对象与搜索匹配，嵌套查询将返回根父文档。

官方文档：https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-nested-query.html

1.在创建索引时进行将type标记为‘nested’

PUT product
{"mappings": {"properties": {"catelogName":{"type": "keyword","index": false,"doc_values": false},"attrs":{"type": "nested","properties":{"attiId":{"type":"long"},"attrName":{"type":"keyword","index": false,"doc_values": false},"attrValue":{"type":"keyword"}}}}}
}

2.修改映射type类型

PUT /my-index-000001
{"mappings": {"properties": {"obj1": {"type": "nested"}}}
}
