Facebook FQL photo_tag table not returning all app

问题:

I'm trying to run a query that returns all the latest tags that happened on my friends photos.

Here is my query:

String query = "SELECT subject, created FROM photo_tag WHERE subject IN (SELECT uid2 FROM friend WHERE uid1 = me()) ORDER BY created DESC LIMIT 200";

This is supposed to return the latest 200 tags performed.

Unfortunately, after looking at my news feed, here are the first few results I get (formatted by SUBJECT at CREATED_TIME)

As you can see, there is a massive gap between 8PM and 4:39PM, and by checking my news feed, there are a WHOLE LOT of photos between these times that should be listed here. Is my FQL query correct? or does the facebook servers just not handle these kinds of queries.. Also, later down the list:

More massive inconsistencies.. Is there any explanation for this?? Thanks for your help!

UPDATE: Of all 200 results, I'm only retrieving about 10 unique subject names UPDATE2: I tried querying a bunch of names that weren't in that list of 10 unique names above, and they resulted in the photos they were tagged in, concluding that their names aren't showing from the larger query above because of any 'privacy' settings or anything. So maybe it's a server side thing?

You will also want to make sure you have both user_photos and friends_photos permissions. Also, friends can opt out of the Facebook platform so that their photos, etc are not available to applications via the Facebook API:
