Join on same bucket not working

SQL++

Summary

Hi, I looked around how to join documents on the same bucket, and tried doing something similar like so:

SELECT n.*, u.* FROM runs n JOIN runs u ON KEYS n.IEMFileVersion;

As you can see I have two documents where the IEMFileVersion are the same:
ss1

But it shows no results.

{
“results”:
}

What am I doing wrong?

Nevermind, I found out you can’t do this yet.
