That is fully expected. Using both pf and qf basically has Solr doing the exact same queries twice, once as specified on fields in qf, then again as a phrase query on fields in pf. If you add pf2 and/or pf3, you can expect further speed drops. If you're sorting by relevancy, using pf with higher boosts than qf generally will make your results better, but it comes at a cost in performance. Thanks, Shawn
