Hi @postkulture, you can retrieve facets using the search method, with the facets search parameter to designate which facets you want to retrieve (using an asterisk * will select them all). If you use an empty query, you will get all the values for each facet. You will also get the hits.
One thing to note is that if you have a lot of records, you may run into inexhaustivity and not get all the hits, nor all the facets. You can check the exhaustiveNbHits parameter to see if you reached exhaustivity. It’s always best to get the complete list of facet values from your original data source when possible.
