How to create a TEXT index in CouchDB 2.0?

问题

I'm reading this article https://cloudant.com/blog/mango-json-vs-text-indexes and I would like to create a TEXT index in my CouchDB

In the Fauxton -> Mango Indexes page, I posted

{
  "index": {
    "fields": [
      {
        "name": "id_str",
        "type": "number"
      }
    ]
  },
  "name": "doc_id",
  "type": "text"
}

...but got a 503 error with the following message:

{"error":"required index service unavailable","reason":"text"}

I wasn't able to find even any related info in their documentation and I feel really lost now.

So:

1. How to create a TEXT index in CouchDB?
2. Where can I find a decent introduction to indexes in CouchDB?

Please help, thanks.

This error is different than an unknown index type since Couchdb 2.0 has stubs for text indexes, but doesn't directly implement them. These stubs depend on a dreyfus text index module provided by cloudant.

A guide to configuring and recompiling couchdb 2.0+ with Dreyfus (and its Clouseau dependency) can be found here. (I verified that these instructions work with the latest couchdb and dreyfus master branches as of 2017-04-22.)
