Elasticsearch - dynamic mapping with multi-field support - elasticsearch

Question

Is it possible to add new fields with multi-field support dynamically?
My index has properties that will only be known at indexing time. So these fields will be included with dynamic mapping.
But, when a new field is added dynamically, I need it to be mapped as text and with three sub-fields: keyword, date (if it fits with dynamic_date_formats) and long.
With these three sub-fields I will be able to search and aggregate many queries with maximum performance.
I know I can do a "pre" mapping my index with these "dynamic fields" using nested field with key and value properties so I can create the value property with these three sub-fields. But I don't want to create a nested key/value field because it's not very fast when performing aggregations with a lot of documents.

I found it.
Dynamic templates is the answer.
Very simple :)
{
"mappings": {
"doc": {
"dynamic_templates": [
{
"objs": {
"match_mapping_type": "object",
"mapping": {
"type": "{dynamic_type}"
}
}
},
{
"attrs": {
"match_mapping_type": "*",
"mapping": {
"type": "text",
"fields": {
"raw": {
"type": "keyword"
},
"long": {

}
}
}
}
