ElasticSearch terms aggregation on tokenized field

问题

when i do terms aggregation on string field (with whitespace tokenizer) i have results for each word (token), but i need results for whole strings. How can i do aggregation on string field like terms but group output by whole string, not by tokens?

I already saw this solutions: ElasticSearch term aggregation Terms aggregation based on unique key but they are based on keyword tokenizer

I can't use keyword tokenizer, because of i wan't apply stopwords filter while indexing

I just had the same problem, and came here looking for a solution.

And then it dawned on me. there's a .raw (unanalyzed) field, and it worked. The solution was to use it.

So the aggregation went from:

{
  "aggs": {
    "keys": {
      "terms": {
        "size": 0,
        "field": "key"
}}}}}

to:

{
  "aggs": {
    "keys": {
      "terms": {
        "size": 0,
        "field": "key.raw"
}}}}}
