I think I'm overlooking something obvious here. If I have data indexed  
with the mapper-attachment like so:

{

- \_index: index
- \_type: type
- \_id: s8SSO7frShGcVH8P8rSaaw
- \_version: 1
- \_score: 1
- \_source: {
  - id: { ... }
  - user: { ... }
  - date\_created: 1321286179
  - date\_updated: 1321286179
  - visibility: visible
  - title: Linguiste
  - file: {
    - \_content\_type: application/pdf
    - content:JVBERi0xLjUNCiW1tbW...  
}  
}

}

how can I query on content type? I thought I would be able to do something  
like:

{  
"query": {  
"term": {  
"file.\_content\_type": "pdf"  
}  
}  
}

but no dice. Where am I going wrong?

Thanks!

Its called content\_type, or in your case, file.content\_type should work. The \_content\_type option in the json is a hint to the parser (which might be able to derive it automatically if not provided), and then its indexed under content\_type.
