P: Allow facial recognition feature to re-index a folder/collection

Here is another photo that had faces LR6 could not find. These faces had previously been found in other photos. I am finding that LR6 tends to put the bounding rectangle at the upper left as in this photo and the one I posted previously: In other words LR6 has no clue whether there is a picture or not. Moving the rectangle and identifying the face, did not result in improved performance on similar photos.

Facial Recognition in LR6 is very poor. Sometimes it does not put the square over the face even in a portrait. In an example folder of 120 photos, the suggested people rectangle was towards the upper left of the photo, unrelated to where the face was, in most photos. Moving the rectangle is a painful task, I have 120,000 photos in my catalog. Sometimes, LR6 guessed correctly even if only part of the face was visible. What then, if I accept, does that mess up all future matches. If I reject, how to I get it to look for the face again. If I move the rectangle, will I live long enough to do all 120,000 photos. Please fix this soon. It is potentially a great tool. Attached is a photo with a face that LR6 could not find.

Or when people have rejected suggested face regions from a large number of photos (which has happened a lot).

It does some good if lightroom crashes and the face indexing stops halfway through and doesn't restart.

Re-indexing on its own is not a lot of good unless it is changed so that it recognises the 50% of faces it ignored the first time!

Absolutely right! Re-indexing seems an obvious need.

I did a photo shoot this weekend. Is there a way to export the files as a separate catalog, then delete all facial recognition information from that catalog, re-start facial recognition on that catalog, and reimport it to my working catalog?

It would also be very nice if the facial recognition software was aware of context, because a lot of photos are already tagged with names, just not connected to the faces. If someone's name is in the keywords, chances are that the face is them, not someone that looks vaguely like them.

It would also be nice to restrict the face matching to certain groups, I'm not going to have a lot of my aikido friends show up in a photoshoot at a dance, and not a lot of dancers will show up at a family gathering, and so forth.

My computer crashed, apparently halfway through searching for faces from a photo shoot and it has missed most of them. How do I rerun it?

Completely agree. The granularity is a feature offered in Picasa.
