I am new to elasticsearch, so I may not be constructing the mapping in a  
correct way. But, my mapping looks as follows:

/myindex/messages/\_mapping

{

```
“messages“: {

    "properties": {

        "author": {

            "type": "String"

        },

        “pipe_id": {

            "type": "String"

        },

        "files": {                

                "type": "nested",

                "properties": {

                    "file" : {

                        "type": "attachment", 

                        "path": "full", 

                        "fields":

                        {

                        "file_author": {

                            "type": "String"

                        },

                        "file_id": {

                            "type": "String"

                        },

                        "file_mimetype": {

                            "type": "String"

                        },

                        "filename": {

                            "type": "String"

                        },

                        "content" : { 

```

"term\_vector":"with\_positions\_offsets", "store":"yes", "type": "String" }

```
                        }

                    }

                }

        },

        "tags": {

            "properties": {

                "tag_id": {

                    "type": "String"

                },

                "tag_name": {

                    "type": "String"

                }

            },

            "type": "nested"

        },

        "email": {

            "type": "String"

        },

        “message_description": {

            "type": "String"

        },

        “message_title": {

            "type": "String"

        }

    }

}

```

}

Now I have indexed the document and been able to search correctly on the  
attachments. But the highlighting on the "content" does not work. My query  
is as follows:

POST /myindex/messages/\_search

{

```
"query" : {

"query_string" : {

  "query" : "music"

}

```

},

"highlight": {

```
  "fields": {

      "files.file.content" : {}

  }

```

}

}

It matches the term "music" in my file and displays the base 64 encoded  
string but there is no highlight field. Please suggest if my mapping is  
correct and why am I not getting the highlighted result?

I solved this problem by setting "include\_in\_root" to "true" for the nested  
attachment.
