Hello, I am having trouble updating mappings. I have read:  
[http://www.elasticsearch.com/docs/elasticsearch/rest\_api/admin/indices/put\_mapping/](http://www.elasticsearch.com/docs/elasticsearch/rest_api/admin/indices/put_mapping/)  
and the "Doubt on updating mappings" article in the forum.

I want to change a field from being not stored to stored. I tried to re-run the the json mapping (with the update) through curl , and I keep getting:  
{"error":"Merge failed with failures [[Mapper [receivedDate] exists, can't merge]]"}

To update a mapping, do I just re-run the same mappings json I used to create the mappings (with the changes)? (That is what I'm trying and it is not working.) If not, what do I do?

Also, it is not clear to me where I put the ignore\_conflicts param. Is that what I need? I wasn't sure on what level of the json tp put it in. If that is what I need, could you please give a little more information about where to drop it into the json or the url?

Thanks,  
John

You can't change a field form not being stored to being stored. ignore  
conflicts will simply ignore this conflict, but not apply it. You will need  
to reindex your index.
