هل يمكن أن تتضمن البحث في الوسوم استبعاد وسم معين؟

I have a situation where I’d like to tag topics when I send them to a downstream summary, then exclude those topics from future searches when I look for the next one to summarize and send.

Is there a way to search on ‘not’ a tag (-tag, for instance) so I can exclude those tagged prior topics?

We actually do support searching for -tag:, see New search operator "not" for tags only - #32 by kasiabulat.

For example, to search for topics in the feature not tagged pr-welcome, search for
#feature -tag:pr-welcome

Excellent! Works great, and cool that one can code tags into the initial search box… always more to learn.
