Amazon.com on Thursday unveiled a new service that lets bookworms search through pages of thousands of books available on its online store.

The service, dubbed "Search Inside the Book," lets people type in any keyword and receive results for all the pages and titles of various books that contain that term. In the past, Amazon customers could search only by author name, title or keyword. The search feature works with around 120,000 titles from 190 publishers, which translates into some 33 million pages of searchable text.

That could be a useful feature, but I don't see how it is going to help someone decide if they want to buy the book or not.

I guess if it is a reference book and they need to know how many times it is mentioned in it, but other than that it seems kind of silly to me.
