Search source url history

[Yay295]

I'd like to be able to search the source url history for all images. Currently you can can search for an image by its source url with the source_url term, but it doesn't search in the source history.

For example, I was looking for the now-deleted image http://oze-jp.deviantart.com/art/Oh-my-492366820. Searching for the ID (source_url:*492366820*) doesn't return any results, but Derpibooru does actually have the image, and the URL I was looking for is in its source history.
