This week, the Securities and Exchange Commission (SEC) added full-text searching to public company financial disclosures going back the last four years in their EDGAR database. They have gone all Google with a single search box with results appearing below.  But that's about where the comparison ends.  Simple searches will yield thousands of results, quickly sending you the "Advanced Search" link to narrow down the list.  While it appears the search engine will need some honing, I imagine having full-text search capability will be a huge boon to lawyers, paralegals, accounts, and financial professionals dealing with SEC filings.
