Hi guys. After several hours of hacking around, I discovered that the
problem I was working on was the result of a string ("1980-01-01") being
parsed and indexed as a date instead of a string.
Is there a way to find out how ES decided to index a document? It'd be very
helpful to be able to see how each field was indexed, where dynamic
templates were applied, etc.

You can ask ES for the current mapping on a given type.
[http://localhost:9200/index/type/\_mapping](http://localhost:9200/index/type/_mapping)
You can define your own mapping by putting it before indexing your first document.
PUT [http://localhost:9200/index/type/\_mapping](http://localhost:9200/index/type/_mapping)
See [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/api/admin-indices-put-mapping.html)

Hey David. Thanks for reminding me about that. I knew you could GET the
mapping, but didn't realize that doing so also shows the mapping for fields
created by dynamic templates.
Cheers!
