ElasticSearch - Dot in field name of nested object - elasticsearch

Question

I have data of this form:
{
"workers": {
"worker.1": {
"jobs": 1234
},
},
"total_jobs": 1234
}
and I'm trying to deal with having the "dot" in the field-name. I tried this mapping:
{
"worker_stats": {
"properties": {
"workers": {
"type": "object",
"properties": {
"worker.1": {
"type": "nested",
"index_name": "worker_1",
"properties": {
"jobs": {
"type": "integer"
}
}
}
}
},
"total_jobs": {
"type": "integer"
}
}
}
}
but when I fetch my mapping, the index_name is no-where to be seen, and when I add a document, it's still got the dot.
Ultimately, I'm just trying to do some aggregations:
{
"query": {
"filtered": {
"query": {
"match_all": {}
}
}
},
"aggs": {
"worker1_stats": {
"aggs": {
"stats": {
"stats": {
"field": "workers.worker.1.jobs"
}
}
},
"nested": {
"path": "workers.worker.1"
}
}
}
}
but the dot interferes.
What can I do to deal with this dot? Is there a way to use script instead of field? (Is my use of nested even correct?

I think you can use a index_name, path, and type : object in your mapping to change the name of that field during indexing.
Here is my example:
PUT /twitter/
{
"settings" : {
"number_of_shards" : 5,
"number_of_replicas" : 0
},
"mappings": {
"tweet":{
"properties": {
"desc.youbet":{"type":"object","path":"just_name",
"properties": {
"one": {
"type": "integer", "index_name":"one"
}
}
}
}
}
}
}
PUT /twitter/tweet/1
{
"name":"chicken",
"desc.youbet":{
"one":1,
}
}
PUT /twitter/tweet/2
{
"name":"chicken",
"desc.youbet":{
"one":1,
}
}
You can now used desc to do operations on and search for what was one in your document so this:
POST /twitter/tweet/_search
{
"query": {"match_all": {}},
"aggs":{
"stats": {
"stats": {"field": "one"}
}
}, "size":0
}
Results in something like this:
{
"took": 2,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"hits": {
"total": 2,
"max_score": 0,
"hits": []
},
"aggregations": {
"stats": {
"count": 2,
"min": 1,
"max": 1,
"avg": 1,
"sum": 2
}
}
}
