How this works
The headline distinguishes candidate upper bounds (index prefilter), estimated matches (a projection from checked samples) and verified matches (an exact count established by the engine). The index contains 131,219,565 homepage documents, one homepage per hostname, including subdomains. The source index was promoted 2026-09-22 and follows a quarterly rebuild schedule. The sample date is when this query was checked against the stored index, not a new crawl of each example site.
