Hi guys,

How to reproduce: [https://gist.github.com/rmat0n/7b6f4f0398dc5f0966b4](https://gist.github.com/rmat0n/7b6f4f0398dc5f0966b4)

I created 2 mapping with a testtext field on both, the difference is that  
each mapping have a different index\_name for the field: the first mapping  
use 1.testtext and the second mapping use 2.testtext.  
Then putting 1 object on each mapping. Here I have 2 objects with the same  
field test text but on different mappings.

Now I query using the exists filter _(also tested using the exists syntax  
in the query\_string)_ on the field name:

{  
"filter": {  
"exists": {  
"field" : "testtext"  
}  
}  
}

This query only returns the document added to the first mapping and not the document added to the second mapping.  
I expected to get back the 2 objects because both have the testtext field.

Reading the documentation [http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-object-type.html#\_path\_3](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-object-type.html#_path_3): _there is an automatic detection from logical full path and into the **index\_name** and vice versa_.  
So, even if I don't query the index\_name, I should be able to get it by the field name _(path)_.  
I could have expected to get both or none but only the first seems weird. Maybe I am missing something.

Thanks in advance.
