As Google continues to improve other areas of its broad ecosystem, it's always great to see that the company hasn't abandoned its search simplification roots. A spokesperson for the company told us, "we recently added the ability to search within Gmail attachments as part of our ongoing efforts to improve search." This potential time-saver plays nice with Word docs, PDFs, PPTs and many other file extensions. Currently in its infancy, some of your older attachments may not have been indexed yet, so you might not be able to "share" last year's term paper with your younger sibling until Google brings the feature up to speed. However, if you're just looking to locate that recently received Word doc filled with notes from your study buddy, then have at it.
