Google will stop at nothing in its quest to index the world's information. Last year it ate through 100 exabytes of data, but there's still a lot that it can't get access to. Known as the deep web (or hidden web, or invisible web, etc.), it is estimated that the majority of online data is hidden safely from Google's prying eyes -- private intranets, unlinked pages, some non-textual content, and until today dynamic content returned via form input was all inaccessible to the search engine. Google today announced that its Googlebot web crawler would begin to fill out HTML forms and crawl the results.
