I’d like to create a filter in bases to dynamically list all notes that have backlinks from the body of the text to the current note, but no backlinks from any of the frontmatter properties to the currrent note. Is that even possible?
One approach could be to first filter for all backlinks, then explicitly exclude any properties that also contain a backlink. This works well if you only have a limited number of properties that could contain a backlink — you can simply create a separate filter for each one.
If you want to exclude all such properties with a single filter, you could try to expose the frontmatter using file.properties and use a formula to exclude backlinks from there. The values() function may also be helpful in this case. But I have never tried this.
