Questions about finding LDRS
- How does PageSourceSearch know a website uses LDRS?
- By the source itself: The page loads the ldrs package from jsDelivr or unpkg. 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 LDRS?
- No. The page lists the 50 highest-ranked sites in the index whose source holds the keyword, out of 15 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 LDRS 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 (cdn\.jsdelivr\.net/npm|unpkg\.com)/ldrs with wp-content/plugins/ lists the WordPress sites that use LDRS.
