elasticsearch 我在elastisearch中创建了一个多字段，但它'；他没有返回任何数据

我已经用这个创建了一个多字段映射

PUT products/product/_mapping
{
"product": {
  "properties": {
     "brand": {
        "type": "multi_field",
        "fields": {
            "brand_original": {"type": "string"},
            "raw": {"type" : "string", "index" : "not_analyzed"}
        }
     }
  }
}
}

然后我尝试进行查询，但没有得到任何结果：

GET products/product/_search
{
     "_source": [ "brand.raw"],
    "query" : {
       "match" : {
        "brand.raw" : "clinique"
        }
    }
}

结果是：

{
   "took": 2,
   "timed_out": false,
   "_shards": {
      "total": 1,
      "successful": 1,
      "failed": 0
   },
   "hits": {
      "total": 0,
      "max_score": null,
      "hits": []
   }
}

我错过什么了吗？是否可以重新编辑映射？

试试这个：

我创建了如下索引：

DELETE /test_index

PUT /test_index

PUT /test_index/product/_mapping
{
   "product": {
      "properties": {
         "brand": {
            "type": "string",
            "index": "analyzed", 
            "fields": {
               "raw": {
                  "type": "string",
                  "index": "not_analyzed"
               }
            }
         }
      }
   }
}

并添加了两个文档：

POST /test_index/product/_bulk
{"index":{"_id":1}}
{"brand":"first/brand"}
{"index":{"_id":2}}
{"brand":"second/brand"}

现在，如果我像这样使用

“match”

进行查询，我将返回这两个文档

POST /test_index/_search
{
   "query": {
      "match": {
         "brand": "first/brand"
      }
   }
}
...
{
   "took": 4,
   "timed_out": false,
   "_shards": {
      "total": 5,
      "successful": 5,
      "failed": 0
   },
   "hits": {
      "total": 2,
      "max_score": 0.2712221,
      "hits": [
         {
            "_index": "test_index",
            "_type": "product",
            "_id": "1",
            "_score": 0.2712221,
            "_source": {
               "brand": "first/brand"
            }
         },
         {
            "_index": "test_index",
            "_type": "product",
            "_id": "2",
            "_score": 0.028130025,
            "_source": {
               "brand": "second/brand"
            }
         }
      ]
   }
}

但是如果我查询

“brand.raw”

，我只会得到完全匹配的文档：

POST /test_index/_search
{
   "query": {
      "match": {
         "brand.raw": "first/brand"
      }
   }
}
...
{
   "took": 3,
   "timed_out": false,
   "_shards": {
      "total": 5,
      "successful": 5,
      "failed": 0
   },
   "hits": {
      "total": 1,
      "max_score": 0.30685282,
      "hits": [
         {
            "_index": "test_index",
            "_type": "product",
            "_id": "1",
            "_score": 0.30685282,
            "_source": {
               "brand": "first/brand"
            }
         }
      ]
   }
}

下面是我用来测试它的代码：

你能发布一些你已经编制索引的示例数据吗？谢谢，很抱歉Google提出了一个愚蠢的问题，它返回了0.9 elasticsearch版本的文档：（我没有意识到。顺便说一句，现在我有很多布兰德的字段，可以删除这些字段，或者我必须重新创建索引。你不能真的删除字段。我的意思是，你可以在没有这些字段的情况下重新编制单个文档的索引，但如果你要对每个文档都这样做，那么重建索引可能同样容易。
