How does PageSourceSearch know a website uses jQuery UI?

By the source itself: Pages load its files as jquery-ui.min.js or jquery-ui.css, and WordPress enqueues it under jquery-ui-* handles. 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 jQuery UI?

No. The page lists the 50 highest-ranked sites in the index whose source holds the keyword, out of about 833,210 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 jQuery UI 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 jquery-ui with wp-content/plugins/ lists the WordPress sites that use jQuery UI.
