Can I search the catalog for all images with burned highlights?

or for other non-textual meta-data?

LR must "know" this info as I can display it on screen instantaneously for each photo by pressing a single key...
 
To do what you are wanting to do means that Lightroom would need searcheable metadata about overexposure in the catalog.
This does not exist, ergo, what you are after cannot happen...

That kind of information is image data itself, not METAdata.

it takes an instant to color blotches for highlights, and the overlay is certainly not part of the image

it would be trivial for them to program this
 
What Lightroom would have to do is start keeping a record of each image's clipping status. Which could be trivial, but that's usually not the issue. What keeps "easy" features from being developed is prioritizing them with other "easy" features, of which there are usually a few hundred different requests.

Another factor is how do you implement the feature so that it's not incomplete. For example, if there's going to be a feature that tracks blown highlights, someone is going to ask that it should also track images with plugged shadows, and someone else (like me) is going to want to list which images are out of gamut for a specific soft proof condition, since these are all aspects of the same feature.

A good way to try to get it implemented is to go to the official Adobe feature request page for Lightroom and submit it there, and then rally people to vote for your request to get it ahead of the other competing feature requests. It looks like it will need a couple hundred votes to get it into the top ten.

The overlay is created on the fly from the image when you request it. That information isn't in the database, only in the image. That means that you cannot search the catalogue for it. It takes only an instant because building it is a relatively simple process.
 
Thinking through this a little more...for a raw image, you can't have a clipping overlay until Lightroom has rendered the image, because the clipping has to be based on Lightroom develop settings, not whatever is in a JPEG preview. An accurate clipping overlay is not available until the image has gone through the same processing that generates a Lightroom preview. This is partly why the clipping display is only provided in the Develop module.

What I'm getting at is that this feature may have a significant performance cost when scaled. Although the clipping overlay for one image seems to appear instantly appears with a single J key press, the work was done behind the scenes first. Scaling that up, if you want to see which of 400 unedited images have clipped highlights, Lightroom may not be able to deliver that information to you until it has done at least an initial rendering of the 400 images. In other words, the time required to give you that list of clipped unedited images might be similar to the time required to build Lightroom previews for 400 images.

If you believe this to be so important feel free to make a request direct to Adobe - complaining on this forum does nothing since this forum is not an ADOBE forum....
