Hi Pete, bq parameter works with q,alt query parameter. If you are passing the search criteria using q.alt query parameter then this bq parameter comes into picture. Also, q.alt doesnt support field boosting.
If you want to boost the records with their field value then you must use q query parameter instead of q.alt. 'q' parameter actually uses qf parameters from solrConfig for field boosting. Let me know if you have any questions.
