Hi, I need some suggestions. I need a list of all facets available in a collection. And I have a facet defined by a wildcard like

tag.*

in the schema. From my observation - if I get a collection via the GET API, I get the current schema which will include facets like

tag.something1

,

tag.something2

. Now my confusions are - 1. is this the proper way to get the list of all current facets? 2. would this approach be feature proof? (I mean if there is any chance to not providing this info via this API) 3. suppose,

tag.something1

had only one one record and I have removed it. should I still expect to have facet in the schema? 4. is there any limitation of such dynamic facets? in terms of the number of facets and performance in the future? Thanks!
