I have this object:

document  
{  
Title:string,  
Id:integer  
Tags:List  
}

Tag  
{  
Id:integer,  
Value:string,  
Type:string  
}

When searching for  
document.tags.value I succeed, but when searching for  
document.tags.id, I get no results back.  
Why is this?

Hello Michael,

That's weird, because for me it works on an "autodetected mapping":

So I guess what I understood is not what you have. If that's true, can  
you come up with some more details, like:

- ES version
- mapping
- sample doc

## Best regards, Radu

Hi Radu,

I am using c# NEST for indexing and elasticsearch-head plugin for web  
interface / search, ES 0.19, default mapping. It looks like I/there is a  
problem related to sub objects and similar property names. E.g. document.id  
and tag.id, when changeing tag.id to tag.tagid it works.
