I think there is a confusion between terms Browse and Search and I may have contributed to this by the way I posted my request.
Search options are quite comprehensive and flexible in Content Server as was eloquently explained here.
I was requesting options for browsing where user knows nothing about the content and what to type in search bar and just explores the server using provided GUI.
I am just trying to explain my point and it is up to our generous host to decide what to do. Calibre is a beautiful software to manage ebooks and I am grateful for what we already have.
