ES怎么进行字段添加索引，并保留原有数据

1、先将原索引进行备份

curl -XPOST '192.168.46.163:9200/_reindex?pretty' -H 'Content-Type: application/json' -d'

{

"source": {

"index": "t_finger"

},

"dest": {

"index": "t_finger180131"

}

}'

2、创建新索引

　

curl -XPUT 192.168.46.163:9200/t_finger

curl -XPUT 192.168.46.163:9200/t_finger/_mapping/t_finger?pretty -d '{

"properties":{

"deviceId":{"type":"string"},

"fingerId":{"type":"string"},

"clientId":{"type":"string"},

"browser":{"type":"string"},

"ip":{"type":"string"},

"country":{"type":"string","index":"not_analyzed"}

}

}'

3、迁移数据到新建索引

curl -XPOST '192.168.46.163:9200/_reindex?pretty' -H 'Content-Type: application/json' -d'

{

"source": {

"index": "t_finger180131"

},

"dest": {

"index": "t_finger"

}

}'
