I'm trying to make use of dynamic templates in my mappings, but there  
seems to be a problem when I do so. Curls to duplicate can be found  
here: [https://gist.github.com/969178](https://gist.github.com/969178)

I want to set up a mapping for all "name" fields that appear inside of  
the "contact" type. (In the example curls, there is just one such  
field- the goal would be to support many nested name objects within my  
document.) If I specify the mapping manually, it works exactly as  
intended. If, however, I use a dynamic template to define the  
mappings, it appears as though it ignores the resulting analyzer  
rules. I have done a diff on the mapping both with and without the  
dynamic templates, and the only difference between them is the  
inclusion of the dynamic\_templates property itself. Yet, strangely, I  
experience different behavior when I query the same document.

Am I doing something wrong? Or is this a bug?

Heya,

Thanks for the great repro, its a bug. Opened an issue, a fix is in the oven. [Mapping: dynamic templates of object type do not initialize some mapping data structures (like analyzers lookup) · Issue #929 · elastic/elasticsearch · GitHub](https://github.com/elasticsearch/elasticsearch/issues/929).
