Facet query suggestions index is empty

Hey from an Algolia beginner,
I set up an index with over 500 records which contain title and a tags fields. The title one is a simple string, and the tags one is an array of strings.

I set up a query suggestion index, using facet data, following this guide.

When saving the suggestion index settings, the index is being generated, but I always end up with 0 records in it.

How is that possible?
I have not upgraded to a paid plan yet, could that be the reason?

Thank you for your help!

That should work – can you validate that you’ve made both title and tags searchable attributes so Query Suggestions can extract values?

Yes, I can confirm that.

I just checked my query suggestion index, and now I see it has 6 records. Looks like a pretty low number to me :confused:
