在Elasticsearch中实现标签

Question

在Elasticsearch中实现标签搜索的最佳方法是什么？

到目前为止，我的工作情况如下。

我的文档：

{
        "_index": "phaasddb",
        "_type": "phaasddb_type",
        "_id": "id=Container-Image-c234a762-6848-4746-bd39-ab1ec4107e44|pk=Container",
        "_score": 0.5753642,
        "_source": {
          "kind": "Image",
          "name": "DJI_00020356.jpg 27",
          "tags": [
            "RekLabel-Spruce",
            "RekLabel-Nature",
            "RekLabel-Scenery",
            "RekLabel-Flora",
            "RekLabel-Aerial View",
            "RekLabel-Outdoors",
            "RekLabel-Tree",
            "RekLabel-Landscape",
            "RekLabel-Conifer",
            "RekLabel-Plant"
          ],
          "description": "Description",
          "@SequenceNumber": "72247500000000054697124676",
          "location": "Austin",
          "@timestamp": "2018-09-19T22:18:21.915073",
          "pk": "Container",
          "id": "Container-Image-c234a762-6848-4746-bd39-ab1ec4107e44",
          "createdAt": 1536877933
        }
      }

和我的查询：

GET _search
{
  "query": {
    "bool": {
      "must": [
        { "match": { "tags": "Spruce" }},
        { "match": { "tags": "Scenery" }}
      ]
    }
  }
}

“标签”字段只是一个字符串，我正在将一个数组转储到其中。我读到有关嵌套“标签”并可能使用“条款”查询的信息。这很重要吗？我不太了解，到目前为止，这似乎行得通。
