Search in meteor using Easy Search Error: MinimongoEngine

I am currently using this guide to perform an easy search on weather.
http://matteodem.github.io/meteor-easy-search/

It generates an error like the following:

TypeError: MinimongoEngine is not a constructor

This is how I am implementing the search:

Packages installed:

matteodem:easy-search
easy:search
easysearch:components
easysearch:core

client/searchBox.html

<template name="searchBox">
    {{> EasySearch.Input index=playersIndex }}
    <ul>
        {{#EasySearch.Each index=playersIndex }}
            <li>Name of the player: {{name}}</li>
        {{/EasySearch.Each}}
    </ul>
</template>

client/searchBox.js

// On Client
Template.searchBox.helpers({
  playersIndex: () => PlayersIndex,
})

lib/collection.js

import { Index, MinimongoEngine } from 'meteor/easy:search'

// On Client and Server
const Players = new Mongo.Collection('players')
const PlayersIndex = new Index({
  collection: Players,
  fields: ['name'],
  engine: new MinimongoEngine()
})

Some idea of how to solve it, I’m new to meteor, so any help would be appreciated. If I’m doing something wrong, please help.
