You can exclude certain subsets by prefixing the qualifier with a “-”, but this is not supported for the “repo” qualifier in the advanced search. This would be useful particularly when search results are already limited to a user or organization to exclude large repositories that are expected to return false positives for an otherwise targeted query.
Thanks for this feedback! We’re always working to improve GitHub and the GitHub Community Forum, and we consider every suggestion we receive. I’ve logged your feature request in our internal feature request list. Though I can’t guarantee anything or share a timeline for this, I can tell you that it’s been shared with the appropriate teams for consideration.
I have tested, it does not work, can you add this missing feature?
Thanks in advance.
