Ember Route Query Params

i would like to open a new perspective with query params.

That means in my index.hbs i click a button get the value from the input field. After that i will open a new route in my case map-view with path '/map' with query params like

localhost:4200/map/?search=xyz

when i do in my index controller:

queryparams:['location'],
location:null,

and in my route

  actions:{
    search(location){
      this.transitionTo('map-view');
  }
}

i get on my index url instantly

/?location=xcyxyx

but i want on my map routw

localhost:4200/map/?search=xyz
