I have my mappings as such

```
{
"attachment": {
    "properties": {
        "file": {
            "type": "attachment",
            "fields": {
                "title": {
                    "store": "yes"
                },
                "author": {
                    "store": "yes"
                },
                "date": {
                    "store": "yes"
                },
                "keywords": {
                    "store": "yes"
                },
                "content_type": {
                    "store": "yes"
                },
                "file": {
                    "term_vector": "with_positions_offsets",
                    "store": "yes",
                    "index": "analyzed"
                    }
               }
            }
        }
    }
}

```

I want to be able to add custom categories to each file, for example if the  
file is an html file then i want to read the meta tag inside and add those  
categories.

If there is a better approach please let me know so as well, I am just  
trying to get my feet wet with Elasticsearch and just working with the  
attachment plugin for the first time.

also created a SO question on  
it: [http://stackoverflow.com/questions/21711216/how-to-create-custom-categories-for-text-files-indexed-in-elasticsearch-using-th](http://stackoverflow.com/questions/21711216/how-to-create-custom-categories-for-text-files-indexed-in-elasticsearch-using-th)

You can simply add more fields on the same level as file. For example:

"mappings": {  
"doc": {  
"properties" : {  
"file" : {  
"type" : "attachment",  
"fields": {  
"file": { "store": "yes" }  
}  
},  
"meta1": {  
"type": "string",  
"store": "yes"  
}  
}  
}  
}

And then when you index, just specify a value for the "meta1" field in  
addition to your "file" field.

Ooops, forgot to mention "store": "yes" is optional. You don't have to  
store anything if you don't need stored metadata fields.

Thanks, I guess i should be asking how would i set those meta data during  
indexing, is there a feature that ES can perform for me. i saw a way to  
have custom analyzers and was trying those out to see if i can use that to  
set the meta for me if there is something in that document.
