Searching attachments in Gmail

I have been wondering this for about a year now, my answer to myself has always been: "They are probably working on it and by the time you blog about it it will be avalaible for all."

Well, it's been over a year now and it still is not available yet; so here it is:

Why can't I search my attachments from withing Gmail??

I mean, if somebody sends me an attachment in an email, there is no way for me to search within this attachment that I know of. The only workaround I found so far is to import the attachment to Google docs and then it becomes searchable from within Google docs. But I mean this is really cumbersome.

Isn't Google supposed to organize the world's information and make it accessible and useful? How about my own information?
