Not sure where to post that, but it's currently (as far as I know) impossible to search the content of a link.
Even the field "any field contains" doesn't query that part of album pages.
I'd like to request that feature if it's possible, thanks.
As a simple example, if you currently type in "mora.jp", there's only
one result, when obviously a bunch more should display.
Thanks to consider that little change, or maybe add a new field "search link" / "available at".
