elasticsearch - 如何存储所有属性的原始值？

Question

如何存储 elasticsearch 中所有属性的原始值？

我需要原始值进行聚合，属性是未知的。

更新:

希望所有属性都是

{
   "type": "string",
   "fields": { 
        "raw": { 
            "type": "string", 
            "index": "not_analyzed"
        }
    } 
}

而属性是动态的

提前致谢。

You have to use PUT method to add data to elasticsearch. 

Example: 

`$ curl -XPUT 'http://localhost:9200/products/product/123' -d '{
  "ProductID": 123,
  "SellingPrice": 1200.00,
  "DiscountAmount":0.00,
  "Discount": {
    "Type": "percentage",
    "Amount": 25,
    "StartDate": "2014-08-13T12:05:00",
    "EndDate": "2014-12-31T12:10:00"
  }
}'`

CURL library can be used to send data to your elasticsearch. For testing purpose you can use [chrome sense plugin][1]. 

For getting aggregation use POST or GET method. 

Example:

`$ curl -XGET 'http://localhost:9200/products/product/_search?search_type=count' -d '{
  "aggregations": {
    "my_agg": {
      "terms": {
        "field": "SellingPrice"
      }
    }
  }
}
'`

Above example will return aggregation result as below:

 `{
   "took": 48,
   "timed_out": false,
   "_shards": {
      "total": 5,
      "successful": 5,
      "failed": 0
   },
   "hits": {
      "total": 117,
      "max_score": 0,
      "hits": []
   },
   "aggregations": {
      "my_agg": {
         "doc_count_error_upper_bound": 0,
         "sum_other_doc_count": 0,
         "buckets": [
            {
               "key": 1200,
               "doc_count": 1
            }
         ]
      }
   }
}`
