Hiding common fields in ES response

Question

Is there any way I can hide some of the common fields which are being returned as a response by ES.

e.g if I get the response as below:

{
  "took": 74,
  "timed_out": false,
  "_shards": {
    "total": 15,
    "successful": 15,
    "failed": 0
  },
  "hits": {
    "total": 24,
    "max_score": 0.15932977,
    "hits": [
      {
        "_index": "prashant",
        "_type": "session",
        "_id": "LeIDrUNmSKGC5Sl9Y8O0Zw",
        "_score": 0.15932977,
        "fields": {
          "Time": [
            "2014-01-08T15:01:26"
          ]
        }
      },
      {
        "_index": "prashant",
        "_type": "session",
        "_id": "dlpQGXk_TOyfNnUEG6skeQ",
        "_score": 0.14296037,
        "fields": {
          "Time": [
            "2014-01-08T15:01:26"
          ]
        }
      }
    ]
  }
}

Now I want the ES to respond without took, timed_out, _shards,total, successful, failed value as well I don't want the Name of the _index, _type as I am executing the query to particular index and type.

So is there a way to filter the ES response in that way?

Use the "filter_path" query parameter. In your example, to only include the _source and _id fields for all results (and thereby exclude all the other metadata in the response) use:

http://your-es-cluster?filter_path=hits.hits._source,hits.hits._id

Its been in the rest api since 1.6 I think.

To further filter and limit the fields in the _source, use the normal _source parameter filtering. For example:

http://your-es-cluster?filter_path=hits.hits._source,hits.hits._id&_source=Time

You can limit the search response by specifying the fields to be returned in the search query part of your request.

"search_request": {
  "fields": [ "title", "content" ],
  "query": ...
},

This is a standard field filter of Elasticsearch, it's not clustering-specific. Remember that you must include the fields that will be used for clustering later on. See the plugin's documentation ("A bit more about field mapping").

Is there any way to filter the common return fields like _index, _type which is same for all records if I am running the query to particular index and type – Prashant Mar 19 '14 at 13:04
