No. The page lists the 50 highest-ranked sites in the index whose source holds the keyword, out of about 5 websites that do; the count is the index's estimate at the time the list was computed. Run the keyword as a search to page through all of them, or add a kind or date filter.
How do I find websites that use Knak together with another technology?
