Yes and no. If you wait to indicate # of results from filter choices you run the risk of the user "drilling down" to zero. That is...pick...pick...pick...Go.."No results for your filters". That's not fun either. I find I use filters - again Home Depot is a good example of bad - because the search is too loose. I'll enter a brand in the search term and have to use filters to pick only the brand I want to see. The search should first try to answer the users search, not dump more possible products in the customers' face hoping the buy sonething.
