Google Sheds Light On 'Dark Web' With PDF Search
CWmike writes "Google this week took another step in its effort to shed light on the so-called Dark Web, announcing that its search engine can now search scanned documents in a PDF. In April, Google announced that it was looking for ways for its search engine to index HTML forms such as drop-down boxes or select menus that otherwise couldn't be found or indexed."
An announcement is available at the official Google blog, and it contains some demonstration searches.
Google has long since favoured PDFs - and gives them boosted results, under the guise that anyone who makes a PDF has something serious to say, I guess.
You may have noticed of late that people are wise to this - there are a bunch of sites that are embedding popular search terms / results in PDF files, and clustering their sites with adverts.
