I'm on Windows 11 LrC latest from February build.

I shot a band this weekend; 5 members. About 545 shots. Same date, within a 5 hour range. There are occasional shots with random folks but not many.

I imported, processed, culled, cropped, and de-noised (very low light on an old D300s) and am ready to export for them. I thought it would be very nice to just auto-tag these 5 people in good shots before doing so.

I opened the people view; it began identifying folks. I named the main five as they popped up. I gave random names to four consistent folks who showed up in the last 20 shots or so just to get them out of my hair (singer one, gospel two, etc). Now that I had the initial categories named, I went through the stack of similar faces (which had been mostly mididentified with people from my historical catalog) correcting them and confirming them, and thought I was done.

But oh no - Of the 500+ images, only 20 or 30 were identified as having faces at all, much less these 5. So going back to the folder and then to people view, suddenly a few more were ID'ed. I can't seem to find a way to force LrC to scan these images and tag every face it sees. I can understand it missing some in profile, or shaded or turned away, etc but most of these are full-on almost direct matches for the ones I've identified (identical lighting, conditions, lens, etc).

I want to:
* force a scan of only this folder (date) of images for all faces.
* identify the faces it can by comparing only with face data from this date (I have 200,000+ images in my master catalog and all of that is irrelevant to this shoot).
* Even if it must use all face data, I want it to start it and just let it grind away overnight and nail down these few people because I am too lazy to do it manually.
* I just had an idea that perhaps lightroom.adobe.com would do this better due to cloud process so I have created a collection and 'synced' it up (my master catalog is the one synced, but mostly for going the opposite direction: automatically importing my cell phone 'roll' into the catalog so I don't lose random stuff - sometimes I will go this direction though and I've kicked that off now - and if I do, and find that face tagging works much better in the cloud, is it fair to say these people will all be synced down into LrC?
* I have previously found rather accidentally that uploading exports to Google Photos (useful for sharing with non-adobe types) does face tagging much more reliably and quickly - but haven't been able to think of a way to export those face areas and keywords back into LrC where my NEFs are. Anyone else do this somehow?

Now that modern CPUs and motherboards are "AI optimized" I believe that Adobe needs to put some serious time into LrC to get this performance and accuracy up to snuff.
 
LrC doesn’t provide an explicit "rescan" button for face detection, but you can try the following to force it:

Temporarily disable face recognition and re-enable it:
- Go to Edit > Catalog Settings > Metadata tab
- Uncheck Automatically detect faces in all photos
- Restart Lightroom
- Re-enable the option and go back to People view

Manually trigger face detection:
- Select all the images in your folder, switch to People View (O key), and wait for LrC to process.
- If faces still aren’t detected, select a single image, go to Library > Find Faces Again, and check if it works.

I'm not sure what you mean -- the Find Faces Again does do an explicit rescan for faces.

I probably jumped into writing without thinking too much—thanks for catching that! :)
