Questions about finding unpkg

How does PageSourceSearch know a website uses unpkg?
By the source itself: Pages reference packages on unpkg.com. PageSourceSearch stores the raw HTML and first-party JavaScript of each crawled site and matches the keyword byte for byte, so every listed site's stored source contains it.
Is this a complete list of websites using unpkg?
No. The page lists the 50 highest-ranked sites in the index whose source holds the keyword, out of about 122,488 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 unpkg together with another technology?
Search for both keywords at once: several terms separated by spaces must all be found on the same site, or with the Same page toggle in the same page. For example unpkg.com/ with wp-content/plugins/ lists the WordPress sites that use unpkg.
