Yahoo Trolls the Invisible Web

Yahoo crawls deep into the Web: I’m nervous that this will lead to people found out about that murder conviction in ‘78.

Yahoo on Tuesday began a systematic effort to draw more content into its searchable database of Web documents, its latest bid to win Web surfers from search rival Google.

The Web portal, based in Sunnyvale, Calif., introduced its Content Acquisition Program designed to index the billions of documents contained in public databases but that are commonly inaccessible to search engines, or what’s called the invisible or deep Web.
