I would like to use the Fetch addon, but can't get the search function running. I have a collection "artists" and want to search by a query string (/!/Fetch/collection/artists/search?query=bla), but I get all results back (not filtered by bla). title and description are searchable in the folder.yaml, I updated it via php please and I can also see it in every artist collection file. I tried with index (!/Fetch/collection/artists/search?query=Bla&index=collection/artists) but still get all results.
What am I missing?
