Using more than one Custom tag in resource selection

If you have a specific technical inquiry, construct your post with the following:

Summary

It seems Kolibr does not support multi-tag selection when searching for questions for an Exercise. I added these tags to the questions:
“tags”: [“Topic: States of matter”, “Difficulty: hard”, “type: single_answer”]
When I try to search using more than one tag it returns “0 selected”
Other ways I’ve tried:

  1. Search step by step but after the first search, the Search option disappears.
  2. Going down the folder tree to a specific resource but the Search button disappears

Is there a workaround?
