The number of documents in the collection is about 90 million. The collapse field has about 30 million distinct values, so I guess that qualifies as high cardinality. We used to use result grouping but switched to collapse for improved performance.
The faceting fields are more of a mix, 5-10 fields ranging from around a dozen to around 250,000 distinct values.
