Question

我正在使用elastic4s在ElasticSearch中制作索引。我的代码如下：

var seqBulkDef = SeqBulkCompatibleDefinition
seqBulkDef=seqBulkDef:+request(sha256, parentId, indexMap, ES_INDEX, ES_INDEX_TYPE)
val resp = client.execute (bulk (seqBulkDef)).await(duration)

def request(sha: String, parentId: String, indexMap: Map, index: String, indexType: String): BulkCompatibleDefinition = {
  update(sha) in index / indexType docAsUpsert indexMap parent parentId
}

但它不适用于parentId。我应该如何修改语法。

Answer 1

您需要先添加mapping以建立关系，并指定哪种文档类型应该是子类型的父级。

在scala4s中你需要做这样的事情：

client.execute {
  put mapping "places" / "city" parent ("country") 
}

然后你可以打电话

client.execute {
  update("5") in "places" / "cities" docAsUpsert Map("name" -> "São Paulo") parent "2"
}

Answer 2

update(id).in("places/city").docAsUpsert(write(json)) refresh (RefreshPolicy.IMMEDIATE)

如何在elastic4s中使用父ID进行upsert
