elasticsearch - 更新现有索引上映射的属性

Question

具有此映射:

curl -XPUT 'http://myip:9200/test?pretty' -d'
{
    "mappings": {
        "items": {
           "dynamic": "strict",
           "properties" : {
                "title" : { "type": "string" },
                "body" : { "type": "string" },
                "publish_up" : { "type": "date",
                                 "format" : "yyyy-MM-dd HH:mm:ss",
                                 "copy_to": "publication_date"},
                "publication_date" : { "type": "date",
                                       "format" : "yyyy-MM-dd HH:mm:ss"},

        }}}}'

我想将属性 publication_date更改为 "store" : "yes"，以便返回值 using fields。这是我的尝试:

curl -X PUT 'http://myip:9200/test/_mapping/items?ignore_conflicts=true' -d '{
  "items": {
    "properties": {
      "publication_date": {
        "type": "date",
        "format" : "yyyy-MM-dd HH:mm:ss",
        "store" : "yes"
}}}}'

但是我得到了错误

{"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"Mapper for [publication_date] conflicts with existing mapping in other types:\n[mapper [publication_date] has different [store] values]"}],"type":"illegal_argument_exception","reason":"Mapper for [publication_date] conflicts with existing mapping in other types:\n[mapper [publication_date] has different [store] values]"},"status":400}

有什么帮助吗？提前致谢。

PS:我正在使用ES 2.3

一旦将文档写入ES(ES 2以上版本)，就无法更新映射。

由于更改映射将意味着使已建立索引的文档失效，因此您需要使用正确的映射创建新索引，然后将数据重新索引到该索引中。
