@teolemon @raphael0202 We don't seem to share the same taxonomy tags, e.g. categories vs category.
I don't really mind, it's just that we would need a new specific TaxonomyType class. Which kind of make sense anyway as we currently don't have a "brand" taxonomy type and Elastic Search does have one AFAIK.
