Add ability to show issues which ARE one set of tags and NOT in a certain tag.

This repeatedly came up during the Git migration, wanting to find issues tagged with one tag, say 'git sprint 10' that were not tagged 'git phase two'

I think this belongs as a request against Project issue tracking. Definitely not a Git Community Testing Issue.

Just marked #1201906: Allow advanced issue search to factor in both included and excluded tags duplicate, which has a screenshot and some discussion about the UI.

Note, these filters are currently added via _project_issue_views_add_taxonomy_filters() in project_issue.views_default.inc so it might be a bit trickier to handle this there.

An alternate approach could be to alter the default views via drupalorg.module or something. However, I'm okay just doing this inside project_issue itself, since any site using issue tags probably wants this kind of thing. If you have trouble, let me know and I can try to make time to help -- however, my life is nuts these days.

I know this is the open issue, but since the interface discussion is over at #1201906-4: Allow advanced issue search to factor in both included and excluded tags, it made more sense to me comment on that one.

Please, let's just use a single issue, this one, to discuss this. That's the point of marking issues closed (duplicate) so that they're closed and we don't keep the conversation going in two places at once.

I also agree with drumm on the less jargony labels.

Re: only working on the site-wide advanced search vs. on the per-project advanced search -- that's because they're separate views, and whatever customizations need to be done to one need to happen to the other. Hence, the implementation details I explained here in comment #2. ;)

Note #2188165: [Regression] View term filter 'is/not empty' and 'not one of' operators do not work "is not one of" is broken anyway.
