MongoDB Atlas Search Definition JSON - String arrays

Question

I have an object like this in a collection in my MongoDB Atlas:

{
  "outer" : {
     "tags" : [
        "astring",
        "another string",
        ...
     ],
     ...
  }
  ...
}

Now I wish to make an index on the array outer.tags among other things. I have made the index definition like this:

{
  "mappings": {
    "dynamic": false,
    "fields": {
      "outer": {
        "dynamic": false,
        "fields": {
          "tags": {
            "dynamic": true
          }
        }
        ...
      }
      ...
    }
  }
}

But I still can't search inside tag, how should I change the definition so to be able to do so?

yes, its there in what actually put in the Mongo Atlas console (hence the ...), but it still didn't help. Nevermind, thanks for your effort, I have fixed it, am posting as a self answer — Divyansh Goenka, Aug 19 '21 at 08:48

It was fixed by simply this:

{
  "mappings": {
    "dynamic": false,
    "fields": {
      "outer": {
        "dynamic": false,
        "fields": {
          "tags": {
            "analyzer": "lucene.simple",
            "searchAnalyzer": "lucene.simple",
            "type": "string"
          }
        }
        ...
      }
      ...
    }
  }
}
