I am totally new to elastic search. So please forgive me if this is a stupid Question and my Questions might have been answered somewhere else already but I couldn't find it. 
I want to use Elastic Search as a search engine for PDF'S and docx's in my network. I used fscrawler to ingest the PDF's to elastic search. Since the documents I want to ingest are in several languages I wanted to use n-graming for stemming. To do so I wanted to update my mapping like this 

```
PUT test/_mappings/_all
{
"mappings": {
    "title": {
      "properties": {
        "title": {
          "type": "text",
          "fields": {
            "de": {
              "type":     "string",
              "analyzer": "german"
            },
            "en": {
              "type":     "string",
              "analyzer": "english"
            },
             "general": { 
              "type":     "string",
              "analyzer": "trigrams"
          }
        }
      }
    }
  }
}
}

```

And now I get this Errormessage

Do you have any idea how i can fix this? Or do you have an idea how I can ingest the files with the right mapping without using fscrawler?
