Previously there was a attribute extractor in v1, which can translate emoji like structure into deadline something: Migrating from Obsidian-Tasks
Yet this is not working on v2 as the feature attribute extraction has been removed. But the underlying mechanism still works: you can add metadata directly to any of the objects in the SilverBullet.
- [ ] some task [deadline: 2025-05-06]
Then you can query deadline with
${
query[[
from index.tag "task"
where deadline == "2025-05-06"
]]
}
