After Unpublishing/Archiving an outdated article, it would be incredibly helpful to be able to query the KB for any articles where that old link exists. That way, it could be corrected - so that our customers aren't met with a dead link down the line.
Of course we try to address all articles that we know about that might contain the old link...but there are a lot of sneaky ones! Would be great to be pro-active on these.
