Faceting on multi-value fields is more a function of the number of terms in the field (and their distribution) rather than the number of hits for a query. That said, perhaps faceting should be able to bail out if there are no hits. Is your question more about why faceting takes so long in general, or why it takes so long if there are no results? If you haven't, try optimizing your index for facet faceting in general. How many docs do you have in your index? As a side note, the way multi-valued faceting currently works, it's actually normally faster if the query returns a large number of hits. -Yonik
