仅使用Elasticsearch选择特定字段

已采纳

I am trying to Get data with specific fields from an Index. I am using olivere elastic client. I tried the following code to select Bedrooms,rooms and location fields from property Index.

    query := elastic.NewBoolQuery()

    query = query.Must(elastic.NewTermQuery("rooms", "1"))
    query = query.Must(elastic.NewTermQuery("bedrooms", "1"))

    get1, err := client.Search("Bedrooms", "rooms", "location").
        Index("property").
        //Type("doc").
        Query(query).
        Sort("id", true).
        Size(5000).
        Do(ctx)
    if err != nil {
        // Handle error
        panic(err)
    }

    You can achieve this by using the Fields

    query := elastic.NewBoolQuery()
    
    query = query.Must(elastic.NewTermQuery("rooms", "1"))
    query = query.Must(elastic.NewTermQuery("bedrooms", "1"))
    
    get1, err := client.Search("Bedrooms", "rooms", "location").
        Index("property").
        //Type("doc").
        Query(query).
        Sort("id", true).
        Fields("field1","field2")
        Size(5000).
        Do(ctx)
    if err != nil {
        // Handle error
        panic(err)
    }
