Greaseonkey script adds a pseudo-search box to Google Reader
Continuing the buzz surrounding the new Google Reader, 3rd party Greasemonkey scripts are cropping up that either modify or add much-requested features (like integrating it with Gmail). At the top of this request list (or at least near it) is search - after all, it is a Google product. Unfortunately, the Reader team's own Mihai Parparita has explained in the product's Google Group that search is a bit tricky right now - but they're working on it.
While you wait though, why not add at least some basic search functionality with this Greasemonkey script? Be warned though, as by 'basic' I mean 'it can only search a single feed you're reading, or all blogs across the blogosphere, via Google's Blog Search.' For now, it can't search multiple blogs (a limit of the Blog Search engine itself) or folders of feeds in Reader, but hey - it's a start. On the plus side, the author is open to suggestions if anyone knows of an engine better suited to the task of searching multiple sites at once, so throw your two cents in if you want to make the only Google Reader search that much better.
