Quicksearch not showing calendar items

When you are in the calendar ( day/week/moth view) and you use the top right quicksearch nothing is showing in the views. This did work in clients before 2014R2

STD

- Click on the main calendar

- Right click and create a appointment with TEST123 in the subject

- Post

Now you see the appointment in the day/week/month view

- In the quicksearch type TEST

Nothing shows in the day/week/month view however doing the same in a GW2014 client this does show the result in the day/week/month view.
