Another correction
TABLE prio as Prio, frist as Frist, tags as Tags
FROM (#literatur/todo)
WHERE prio >=4
SORT prio DESC , frist DESC , file.cday ASC, file.name ASC
This code finds files with the tag #literatur/todo. This means, dataview does indeed find tags in the file content. But then dataview can’t list those tags in the column “tags”. In this column it only lists tags that are in frontmatter.
That’s a bit weird.
