Hello,

I'm new to the forum, I have to ask for help to solve a problem, I have an "analyzer" created in the following way that will leave you lines below, however, I need it to work as follows:

1.- Perform the search of certain words in a text string ignoring the insensitive case and accents in the subdocument "Content.content" (currently works).

2.- The same field "contens.content" can search for text with a sensitive case, respecting the values ​​of the text (I can not return anything).

```
​{
​ "template": "pdfscrapy*",
  "settings": {
    "analysis": {
      "analyzer": {
        "folding": {
          "tokenizer": "standard",
          "filter": [
            "lowercase",
            "asciifolding"
          ]
        }
      }
    }
  },
  "mappings": {
    "intranet": {
      "properties": {
        "content": {
          "type": "string",
          "analyzer": "standard"
        },
        "contents": {
          "type": "nested",
          "properties": {
            "content": {
              "type": "string",
              "analyzer": "folding"
            }
          }
        }
      }
    }
  }
}​

```

Thanks for the support
