Source: the SEC’s own EDGAR full-text index, which covers filings from 2001 onward. Results are ordered by EDGAR’s relevance. A filing appearing here means the phrase is in the document, nothing more. EDGAR caps its match count at 10,000 and reports anything above that as a lower bound, so the figure above is a floor rather than an exact total.
