ES 5.5.1 mapping 中 copy_to丢失问题

索引每周重新新建一个，之前多字段match_phrase使用should的方式，速度比较慢，想尝试通过copy_to优化一下，修改后的部分索引结构如下所示：

{

  "mdsindices_20190622": {

    "aliases": {

      "mdsindices": {}

    },

    "mappings": {

      "resume": {

        "properties": {

          "beforeStage": {

            "type": "keyword",

            "store": true

          },

          "candidateName": {

            "type": "text",

            "store": true,

            "fields": {

              "candidateNameOriginal": {

                "type": "keyword"

              }

            },

            "copy_to": [

              "match_full_text"

            ],

            "analyzer": "onechar_analyzer"

          },

          "lastCompanyName": {

            "type": "text",

            "store": true,

            "copy_to": [

              "match_full_text"

            ],

            "analyzer": "onechar_analyzer"

          },

          "lastPositionName": {

            "type": "text",

            "store": true,

            "copy_to": [

              "match_full_text"

            ],

            "analyzer": "onechar_analyzer"

          },

          "lastSchoolName": {

            "type": "text",

            "store": true,

            "copy_to": [

              "match_full_text"

            ],

            "analyzer": "onechar_analyzer"

          },

          "match_full_text": {

            "type": "text",

            "analyzer": "onechar_analyzer"

          }

        }

      }

    },

    "settings": {

      "index": {

        "search": {

          "slowlog": {

            "threshold": {

              "fetch": {

                "warn": "4s",

                "trace": "500ms",

                "debug": "1s",

                "info": "2s"

              },

              "query": {

                "warn": "4s",

                "trace": "500ms",

                "debug": "1s",

                "info": "2s"

              }

            }

          }

        },

        "refresh_interval": "1s",

        "number_of_shards": "10",

        "provided_name": "mdsindices_20190622",

        "max_result_window": "100000",

        "creation_date": "1561136400041",

        "analysis": {

          "analyzer": {

            "onechar_analyzer": {

              "filter": [

                "lowercase"

              ],

              "type": "custom",

              "tokenizer": "onechar"

            }

          }

        },

        "number_of_replicas": "1",

        "uuid": "G-ZAL2ElR9-bWZJcAkDJsw",

        "version": {

          "created": "5050199"

        }

      }

    }

  }

}

在索引建好后，match_full_text不提供给业务查询时，copy_to字段运行正，mapping结构也正常，但是将检索条件切换为match_phrase match_full_text一段时间后，发现老文档可以检索到，新索引的文档却检索不到，但是使用原方式却可以检索到，并且在kibana中查询mdsindices_20190622的结构时发现copy_to属性不存在了，如下：
