Index is not getting created, text index required for $text query - mongoose

mongoose: 5.8.9
node: v12.13.0

After setting up to create index on the schema, mongoose doesn't create the index, After creating a new document there is only ID index nothing newly created. I had done as the document mentioned for creating index but still I can't figure out where I'm making the mistake.

When 

 const ads = await Ad.find({ $text: { $search: "something" } })

Error

MongoError: text index required for $text query

  errmsg: 'text index required for $text query',
  code: 27,
  codeName: 'IndexNotFound',
  name: 'MongoError',
  [Symbol(mongoErrorContextSymbol)]: {}
}

My schema 

import { Schema } from 'mongoose'
import mongoosePaginate from 'mongoose-paginate-v2'
import Local from '../index'

const adSchema = new Schema(
  {
    id: Schema.Types.ObjectId,
    creater: Schema.Types.ObjectId,
    title: { type: String },
    tags: Array,
    description: { type: String, maxlength: 4500, },
  },
  {
    timestamps: true,
    versionKey: false,
    autoIndex: false
  }
)

adSchema.index({ title: 'text', description: 'text', tags: 'text' })
adSchema.plugin(mongoosePaginate)

const Ad = Local.model('Ad', adSchema)

export { Ad as default }

On mongo shell

> myads.getIndexes()
[
    {
        "v" : 2,
        "key" : {
            "_id" : 1
        },
        "name" : "_id_",
        "ns" : "adex.ads"
    }
]

1

2

and from code you need to pass :>>

const blogPosts = await BlogPostModel.find({  $text: { $search: `"${req.query["your-search-query"] }"`  } })

This is how you resolve the same using MongoDB Compass application instead using the mongo console.

Connect to the DB using a connection string like this

mongodb://<user>:<password>@<ip>:<port>/<your db>?authSource=<user>&readPreference=primary&appname=MongoDB%20Compass&directConnection=true&ssl=false

Then select the correct collection from the left pane and then select Indexes tab and create the text index like shown below

Below line: 

adSchema.index({ title: 'text', description: 'text', tags: 'text' })

correctly defines an index on mongoose schema (not on a database). By default mongoose creates indexes when your application starts up (link) however you're preventing it by using autoIndex: false.

So you have to either remove that line or run createIndexes on your model explicitly:

adSchema.index({ title: 'text', description: 'text', tags: 'text' });
const Ad = Local.model('Ad', adSchema);
Ad.createIndexes();
