Adrien Grand a608db122d Search: Remove the `count` search type.
This commit brings the benefits of the `count` search type to search requests
that have a `size` of 0:
 - a single round-trip to shards (no fetch phase)
 - ability to use the query cache

Since `count` now provides no benefits over `query_then_fetch`, it has been
deprecated.

Elasticsearch REST API JSON specification

This repository contains a collection of JSON files which describe the Elasticsearch HTTP API.

Their purpose is to formalize and standardize the API, to facilitate development of libraries and integrations.

Example for the "Create Index" API:

{
  "indices.create": {
    "documentation": "http://www.elastic.co/guide/en/elasticsearch/reference/master/indices-create-index.html",
    "methods": ["PUT", "POST"],
    "url": {
      "path": "/{index}",
      "paths": ["/{index}"],
      "parts": {
        "index": {
          "type" : "string",
          "required" : true,
          "description" : "The name of the index"
        }
      },
      "params": {
        "timeout": {
          "type" : "time",
          "description" : "Explicit operation timeout"
        }
      }
    },
    "body": {
      "description" : "The configuration for the index (`settings` and `mappings`)"
    }
  }
}

The specification contains:

  • The name of the API (indices.create), which usually corresponds to the client calls
  • Link to the documentation at http://elastic.co
  • List of HTTP methods for the endpoint
  • URL specification: path, parts, parameters
  • Whether body is allowed for the endpoint or not and its description

The methods and url.paths elements list all possible HTTP methods and URLs for the endpoint; it is the responsibility of the developer to use this information for a sensible API on the target platform.

Utilities

The repository contains some utilities in the utils directory:

  • The thor api:generate:spec will generate the basic JSON specification from Java source code
  • The thor api:generate:code generates Ruby source code and tests from the specs, and can be extended to generate assets in another programming language

Run bundle install and then thor list in the utils folder.

The full command to generate the api spec is:

thor api:spec:generate --output=myfolder --elasticsearch=/path/to/es
