如果我有处理继承的数据，并且我想查询继承，我如何使用elasticsearch。。。示例
all dealerships
* ford cars
* chevy cars
|
- Oregon Dealerships
* no ford cars
* mazda cars
|
- Portland dealership
| * ford cars
|
- Salem dealership
* subaru cars
Show me all dealerships with ford/mazda/chevy
(Portland)
Show me all dealerships with chevy/Subaru
(Salem)
Show me all dealerships with ford
(all*)(portland)
* assume buckets can be returned as well as dealerships
Show me all dealerships
有没有一种方法可以在弹性搜索中实现这一点？
您可以使用嵌套映射来实现这一点：https://www.elastic.co/guide/en/elasticsearch/reference/current/nested.html
创建索引后，数据将填充到映射的索引中。
然后可以进一步使用嵌套查询：https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-nested-query.html
嵌套查询将帮助您获得问题中提到的结果。
