Elasticsearch Rails基於多個索引的最近記錄

Question

我的Rails應用程序中有兩個模型：Share和Rent。

我開始在我的應用程序中使用ElasticSearch，並且想要一種方法將模型租借和共享給最近的人。

我試過如下：

@response = Elasticsearch::Model.search query:  { 
    "indices": { 
    "indices": [ 
     "shares", 
     "rents" 
    ], 
    "query": { 
     "multi_match": { 
     "query": "Apartament", 
     "fields": [ "tipe"] 
     } 
    }, 
    "no_match_query": { 
     "term": { 
     "": "" 
     } 
    }, 

    } 
} 

但我不知道如何將最新的基於create_at場。

Answer 1

我解決了這個問題，如下所示：

@response = Elasticsearch::Model.search query: { 
     "indices": { 
     "indices": ["shares","rents"], 
     "query": {"match_all": {} 
     } 
    }, 
    size:10, 
    "sort": [ 
     {"created_at": {"order": "desc"}} 
    ] 

Answer 2

Elasticsearch讓你sort根據場，我不熟悉Rails的，但我想你應該試試這個：

@response = Elasticsearch::Model.search query:  { 
    "indices": { 
    "indices": [ 
     "shares", 
     "rents" 
    ], 
    "sort": { 
     "create_at": { 
      "order": "desc" 
     } 
    }, 
    "query": { 
     "multi_match": { 
     "query": "Apartament", 
     "fields": [ "tipe"] 
     } 
    } 
    } 
}
