How to fetch other documents based on the one relationship

Hello @radekwawrzyk

Thanks for posting this question to us.

To get all the articles written by the same author, you need to query by a Content Relationship. We already have discussed the same question in the following thread: Inverse relations - Reverse relationships queries - #3 by samlittlefair

Let me know if this makes sense, or if you have any other questions.

Thanks,
Priyanka
