當搜索文檔的協方差具有很大的支持,如下所述:彈性搜索:協變在DocumentApi

https://www.elastic.co/guide/en/elasticsearch/client/net-api/2.x/covariant-search-results.html

但對於文檔API? - 它是否支持協變?從檢測

例子,其中所有作品:

PUT demo_covariant/car/1 
{ 
    "carname":"ford" 
} 

PUT demo_covariant/boat/2 
{ 
    "boatname":"speedy" 
} 

GET demo_covariant/boat,car/_search 
{ 
"query": {"match_all": {}} 
} 

GET demo_covariant/boat/2 
GET demo_covariant/car/1 

但是,當涉及到查詢多個索引,這將不會產生任何結果:

GET demo_covariant/boat,car/2
