Summary

Introduce negative filtering support

Allowing users to search and filter items by excluding specific criteria instead of only including them. Instead of “show only items that match X”, users could do “show everything except items that match X”.

Examples

• Exclude labels: show items not labeled bug
• Exclude assignees: show items not assigned to John
• Exclude models: show all work-items except a specific module

Why should this be worked on?

Negative filters are essential when working with large backlogs and intake lists. They help users quickly focus on what still requires attention; for example, to exclude models, show all work-items except a specific module. When I have some work items with modules and some without, I can't really make a big filter if I want to show the work-items without filters and only some modules. This significantly improves usability, reduces manual scanning, and supports more advanced workflow and triage scenarios.
