I'm looking at the list of Brands for Dell, and I wonder if it would be useful
to have a link to the issues that have been checked as having No Brand. It may
answer the question people might have as to why some issues are listed in the
displayed Brand fields.

This probably just needs to be supported in search, rather than being a special link. I had thought it was supported, but you can only enter text in the advance search fields.

So it turns out that the advance search form has a special value [IS_EMPTY] that will find all issues that have no value for that field. I had no idea this was a thing. Closing this as it is totally doable now if you know the magic word.
