Facebook Graph API - not returning all comments

Question

I use Facebook Graph API to fetch comments on pages

https://graph.facebook.com/comments/?ids=

but the API is not returning all the comments (only the first level).

In example:

http://www.imedical.cz/aktualni-clanky/aktualni-clanek

https://graph.facebook.com/comments/?ids=http://www.imedical.cz/aktualni-clanky/aktualni-clanek

Is this a bug?

Answer 1

As per the official docs you would set filter=stream to get replies to comments.
