Hello,  
I would like to disable dynamic mappings in the 0.9 release. I  
attempted do do this globally in the elasticsearch.yml by adding this:  
index:  
mapper:  
dynamic: false

I also tried to disable dynamic mappings at index creation with this  
data (in the form of a python dict):  
{'index':{'number\_of\_shards':5,'number\_of\_replicas':0,'mapper':  
{'dynamic':False}}}

Regardless of what I do, when I check the mapping status, I see:  
dynamic: true

Also, when I submit a doc with unknown fields, they end up getting  
indexed.

Is there anything that I am missing? Has anyone else been able to  
disable dynamic mapping?

Many Thanks!  
Paul

When you set the index.mapper.dynamic to false it means that new types will  
not be allowed to be introduced without declaring them first. If you want to  
disable dynamic option on the root object level mapping, then you will need  
to set dynamic to false on the root level object mapping that you define (or  
set it on the default mapping).

Awesome, thanks!!!

I added 'dynamic':False to my put mappings and that did the trick.
