es 修改 mapping 字段類型
一、原索引
PUT /my_index
{
"mappings": {
"_doc": {
"properties": {
"create_date": {
"type": "date",
"format": "yyyy-MM-dd ||yyyy/MM/dd"
}
}
}
}
}
二、創建新索引
PUT /my_index2
{
"mappings": {
"_doc": {
"properties": {
"create_date": {
"type": "text"
}
}
}
}
}
三、同步數據
POST /_reindex
{
"source": {
"index": "my_index",
"size": 5000
},
"dest": {
"index": "my_index2"
}
}
四、刪除原索引
DELETE /my_index
五、設置別名
POST /_aliases
{
"actions": [
{"add": {"index": "my_index2", "alias": "my_index"}}
]
}
