Pls. help a newbie with a search question

[OtisCampbell1959]

I'm a newly registered user. One of the things I've found fascinating about the site, but also frustrating, is the facial image search feature. Some galleries I go into I can click on some random pic or other and below the pic will be a link that says something like "search for additional content". You click on that link and it appears to search the site and return pics of that person's face and similar faces. But I don't see it on all the pics or on all the galleries. Can someone explain it? Or is there a tutorial for it somewhere? I have searched the forums and I can't find a similar question asked anywhere. Thanks much in advance for any help anyone can offer!

Hi,
Its 2 things.
First is the whole site is not indexed yet. We started the facial find option about a month ago. Billions of pictures need to be indexed.
Second is that any new pictures uploaded to the site will not be indexed right away. It will take some time before that happens.

That makes sense. Thank you!
