Do we need to have a Separate office web app server for document preview in SharePoint 2013?

Answer 1

Yes you need Office Web Apps to enable Document Preview.
And Yes that needs a separate server/farm.

In addition to Per's answer: Here is my instruction how to install it: http://melcher.it/2013/05/install-office-web-apps-2013-for-sharepoint-2013-with-pdf-preview/

Follow the reference to Wictor Willens blog for the basic instruction and use my powershell to enable PDF preview.

Answer 3

I just faced a similar problem.

Using a custom display template might not give you the preview features. Resolved it by changing the display template settings to the one that says

"Use the result type to decide"

Hope this helps!
