Since you want to re-populate search results each time a user visits the route.

You can use beforeRouteEnter() in your component as below:

beforeRouteEnter (to, from, next) { 
  next(vm => { 
    // access to component's instance using `vm` .
    // this is done because this navigation guard is called before the component is created.            
    // clear your previously populated search results.            
    // re-populate search results
    vm.initializeSearch();
    next();
  }) 
}
