Facebook returns wrong count of post comments
===

I encounter the following issue in my Android app:

When I create a comment for a post (send a request to FB) I get a successful response (I get the ID for a newly created comment for the post). Good so far.

But if then I immediately call for comments count:

    "SELECT comments.count FROM stream WHERE post_id = '" + postId + "'"

then instead of getting expected 1 (assuming it was the first comment), I get 0 (FB tells there is no comments at all). My question is why this happens? The issue goes away if I wait for some time. E.g., if I wait for about a minute, then FB starts returning expected comments count.

It looks like (just my guess) that FB has no sufficient time to update its indexes (I really believe they use indexing). So I get an obsolete/cached resutls. I wonder is there any means to force getting the freshest data (bypassing any caches on FB side)?
