使用elastic4s从原始JSON创建索引

Question

我需要创建一个索引，其中包含一些上下文完成建议映射，如（https://www.elastic.co/guide/en/elasticsearch/reference/current/suggester-context.html）所示。正如我在https://github.com/sksamuel/elastic4s/issues/452中所看到的，这似乎并不受DSL的支持。

因此，从原始JSON字符串创建索引（类似于原始查询）会很不错。是否有可能实现这一目标？

考虑到你在变量rawMapping中有JSON映射，如下所示：

val rawMapping =
    """{
          "service": {
                  "properties": {
                      "name": {
                          "type" : "string"
                      },
                      "tag": {
                          "type" : "string"
                      },
                      "suggest_field": {
                          "type": "completion",
                          "context": {
                              "color": {
                                  "type": "category",
                                  "path": "color_field",
                                  "default": ["red", "green", "blue"]
                              },
                              "location": {
                                  "type": "geo",
                                  "precision": "5m",
                                  "neighbors": true,
                                  "default": "u33"
                              }
                      }
                  }
              }
              }
          }"""

您可以使用原始映射创建索引，如下所示：

client.execute {
    create index "services" source rawMapping
}
