更新Elasticsearch文档中的字段 [英] Update a field from a Elasticsearch document

问题描述

我需要更新索引到Elasticsearch的文档中的字段。我该怎么做。

I need to update a field in the documents indexed to Elasticsearch . How can i do it.

"redcash_sale": {
"type": "object"
}

将上方字段更新为下方（使为false）：-

update above field to below (make enable false) :-

sale_property_development_j/_mapping/property

{
  "properties": {
    "redcash_sale": {
      "type": "object",
      "enabled": false
    }
  }
}

当我再次映射到elasticsearch时引发错误：-

raising error when I do mapping again to elasticsearch :-

错误

{
"error": {
"root_cause": [
{
"type": "mapper_exception",
"reason": "Can't update attribute for type [_doc.redcash_sale.enabled] in index mapping"
}
],
"type": "mapper_exception",
"reason": "Can't update attribute for type [_doc.redcash_sale.enabled] in index mapping"
},
"status": 500
}

预先感谢！

推荐答案

可以做什么要做的是将您的数据 _reindex 为目标索引，删除原始索引，然后使用新的映射再次 _reindex 为原始索引。

What you can do is to _reindex your data to a dest index, delete your original one and then _reindex again to your original one with the new mapping.

重新索引：

POST _reindex   
{
  "source": {
    "index": "sale_property_development_j"
  },
  "dest": {
    "index": "new_sale_property_development_j"
  }
}

删除原始索引：

DELETE sale_property_development_j

创建请求的映射：

PUT sale_property_development_j
{
   "mappings":{
     "property":{
       "properties": {
         "redcash_sale": {
           "type": "object",
           "enabled": false
          }
       }
     }
  }
}

再次重新索引：

POST _reindex?wait_for_completion=false    
{
  "source": {
    "index": "new_sale_property_development_j"
  },
  "dest": {
    "index": "sale_property_development_j"
  }
}

最后：

DELETE new_sale_property_development_j
