API call to see the mappings of an existing index

Elastic Stack Elasticsearch
1

Greetings,

I have couple of questions:

  1. Is there an API call that outputs the mappings of an existing index? I
    see how to get shard/replica info but could not find the call to print out
    the mappings of each of the fields.
  2. Is there a way to assign defaults (not analyzed etc) to fields that will
    be dynamically added later on?

Pointers to docs if they exist would be much appreciated.

Regards,

I don't know that it's the way, but off the top of my head, I hit http://localhost:9200/_cluster/state which returns among other things the mappings on the nodes.

I'm not sure of exactly what you need to put in here, but it looks like this is what you're looking for: http://www.elasticsearch.com/docs/elasticsearch/index_modules/mapper/#Dynamic_Mappings

Some additions:

  1. The cluster state API gives you back the mappings for indices. In 0.9, if
    you are using the REST API, then there are three endpoints to get all
    mappings, all mappings for an index (or indices), and mappings for a
    specific index and type.

  2. You can use the put mapping API to define in advance mappings for
    specific fields. Is that what you are after?

For 2 I think I was after what Andrew pointed to. I read it again after
Andrew pointed out and this time it made sense.
It's not defining advanced mappings for specific fields as I don't know what
the fields will be. I just want to be able to configure the defaults for any
additional fields to not_analyzed, etc.

I take it I can specify that in the default of dynamic mappings as
described in that page?
