Reverse image search for assets?

I'm not asking for an immediate fix but thought I should post here to see if people agree. There has been a number of complaints in the past talking about how difficult it is to manage your upload assets if they go past a certain amount, for various reasons, and currently we don't have anything to help this except some user scripts. I've been wondering, is it possible to add a reverse image search feature that searches specifically within your upload assets?

It'll allow you to 1. check when you suspect you have already uploaded it before, if I can't confirm my suspicion I'll upload it again just in case, it causes a lot of duplicates 2. find the asset of an image you know you have uploaded, which is buried in your backlog.

Ideally this should also direct you to the page that contains the asset, so you get access to neighboring uploads, uploads are often not standalone.

If it's too difficult to implement for all users, at least make it a builder+ or contributor+ feature?

Been thinking about this too. I have a lot duplicate media assets because I usually upload some posts and forgot to upload it for 2-3 months for various reasons. Plus the pictures I uploaded were mostly came from franchise that can be said to be rather few uploaders here. So my upload assets are usually still there, not yet uploaded. This reverse image search thing will of course help me upload my posts.

For the time being, the "Source" search bar under the "Tags" search bar on the My Uploads page can be used as a substitute. The downside is that you can only trace an asset if you have the exact same source url as the one you used to upload it, meaning a direct image link or a link of the same post from a different source won't work. It also doesn't auto convert urls like other danbooru features, so for example if you have a link of "x.com" you need to change it to "twitter.com" manually.

Also can someone confirm when was this added? I have the impression that it has been there for a long time and I wonder why I didn't make use of it sooner.
