Dynamic Tags in Dataview query - Help?

[FrumpyMonk]

Hello Folks,

I hope you can help. I am trying to use dataview to indicate links to notes that share a single tag or, if that’s not possible, the first tag in the original note’s YAML tag array.

Things I have tried

list from "Research Notes"
Where contains(file.tags, this.file.tags)

and

list from "Research Notes"
Where contains(file.tags, this.file.tags[0])

AND

list from "Research Notes"
Where contains(tags, this.file.tags[0])

All three of these dataview queries produce a “null” result for me no matter how I structure the tags in YAML.

The following works well but defeats my purpose because I have to indicate the tag I want explicitly.

list from "Research Notes"
Where contains(tags, "yellow")

What I’m trying to do

So, in summary, is there any way to design a dataview list query that will read the note’s YAML tags, separate those tags with OR logic and then run a search for other notes that share one of those tags. If that is impossible, is it possible to read a note’s first YAML tag and then run a search for other notes that share the first [0] tag in the array?

Thank you for the assistance,

Kirt

I can see this being a good starting point for a “related” list.

Probably a good case for dataviewjs in combination with a forEach.

Unfortunately, I don’t have much time the next days to investigate, but if you make up a good solution, let us know!

FYI: The most recent update to Dataview allows the following to work:

list from "Research Notes"
Where contains(file.tags, this.file.tags[0]) OR contains(file.tags, this.filetags[1])

I’m not sure if this is an innovation or simply a bug fix. Regardless, although it would be great to see a dataviewjs that accomplishes the same thing, the solution above seems to be the most elegant solution for my needs.

Thanks to everyone who read the original post.
