How to fix a problem with dynamic date templates? - datetime

Question

I have a problem with dynamic date tampletes
I'm using ElasticSearch 6.2.4
My steps:
1) Create index with next settings:
PUT /test1
{
"settings": {
"index":{
"number_of_shards" : 9,
"number_of_replicas" : 0,
"max_rescore_window" : 2000000000,
"max_result_window" : 2000000000
}
},
"mappings": {
"files": {
"properties": {
"Дата добавления в БД": {
"type": "date"
}
},
"numeric_detection": true,
"dynamic_templates": [
{
"integers": {
"match_mapping_type": "long",
"mapping": {
"type": "long"
}
}
},
{
"strings": {
"match_mapping_type": "string",
"mapping": {
"type": "keyword"
}
}
},
{
"dates": {
"match_mapping_type": "date",
"mapping": {
"format": "yyyy-MM-dd HH:mm:ss||yyyy/MM/dd HH:mm:ss||yyyyMMdd_HH:mm:ss",
"type": "date"
}
}
}
]
}
}
}
2) Try to put new records (I have only one)
POST /test1/files/_bulk
{"create":{"_index":"test1","_type":"files","_id":"0"}}
{"Дата добавления в БД":"2019/04/12 11:42:21"}
3) So, I have next output:
{
"took": 1,
"errors": true,
"items": [
{
"create": {
"_index": "test1",
"_type": "files",
"_id": "0",
"status": 400,
"error": {
"type": "mapper_parsing_exception",
"reason": "failed to parse [Дата добавления в БД]",
"caused_by": {
"type": "illegal_argument_exception",
"reason": "Invalid format: \"2019/04/12 11:42:21\" is malformed at \"/04/12 11:42:21\""
}
}
}
}
]
}
I can't understand where is my mistake??
I tried to find some information about this problem in Google, unfortunately, I have no solves of this problem. Maybe, this question is so stupid, but I've already broken my brain.
Please, help me...

I can't fully understand, but this option work:
{
"settings": {
"index":{
"number_of_shards" : 9,
"number_of_replicas" : 0,
"max_rescore_window" : 2000000000,
"max_result_window" : 2000000000
}
},
"mappings": {
"files": {
"dynamic_date_formats": ["yyyy-MM-dd HH:mm:ss","yyyy/MM/dd HH:mm:ss", "yyyyMMdd_HH:mm:ss"],
"numeric_detection": true,
"date_detection": true,
"dynamic_templates": [
{
"integers": {
"match_mapping_type": "long",
"mapping": {
"type": "long"
}
}
},
{
"strings": {
"match_mapping_type": "string",
"mapping": {
"type": "keyword"
}
}
}
]
}
}
}
