Add query string in route map URL

I am using Ember 2.7. Is there any way to specify query parameters in the route map URL

router.js

import Ember from 'ember';
import config from './config/environment';

const Router = Ember.Router.extend({
    location: config.locationType
});

Router.map(function() {
    this.route('index', {path: '/'});

    this.route('books', function() {
        this.route('index', {path: '?page=0&perPage=25'});
        this.route('view', {path: '/view/:bookIdid'});
        this.route('new');
 });

The above code is generating following URL "localhost:4200/books/?page=0&perPage=25", I am not sure why it is adding slash before the query params.

Any help should be appreciated.
