Google Makes PDF Files Searchable
Google, using optical character-recognition technology, can now scan PDF files, turn them back into text and make them available as search results via the “View as HTML” link.
"In the past, scanned documents were rarely included in search results as we couldn't be sure of their content," said Google product manager Evin Levey in a blog post. "We had occasional clues from references to the document -- so you might get a search result with a title but no snippet highlighting your query. Today, that changes."
