Elasticsearch Retrieve token_count standard value from search


I am trying to add a new field into the ElasticSearch index to analyze and store the number of words a text has.

"settings": {
    "analysis": {
        "analyzer": {
            "character_analyzer": {
                "type": "custom",
                "tokenizer": "character_tokenizer"
        "tokenizer": {
            "character_tokenizer": {
                "type": "ngram",
                "min_gram": 1,
                "max_gram": 1
"mappings": {
    "_doc": {
        "dynamic": "strict",
        "properties": {
            "name": {
                "type": "text",
                        "fields": {
                            "words_count": {
                                "type": "token_count",
                                "analyzer": "standard",
                                "store": true

Performing a query I am able to retrieve the documents which have the total words count I request in query:

"size": 1,
"query": {
    "bool" : {
        "must" : {
            "range" : {
                "name.words_count": {
                   "gt": 3

But I would like to retrieve this value on _source results. Is it possible? Am I missing something?

Thanks in advance!

This is not part of the _source, as it was not part of the original JSON. You could however retrieve this as a docvalue field or just enable the store setting in the mapping and the use docvalue_fields or "docvalue_fields": ["name.length"] or "stored_fields": ["name.length"] in the query to retrieve the value.


Thank you Alexander for you answer. It worked as a charm for me.
I have another related question regarding this if you could help me.

I was trying to understand how much space this new stored field could occupy on elastic search. Is there any way to get this metrics through the elastic search?
