Is there a way to search through shared items?

So I've been using the share function of google reader as a mental index to keep track of things of note, sometimes going back to them and reading through, or referencing them. I realize I should probably be pulling pertinant information into a notebook or something, but there's just so much of it and I really don't know what will be useful until i remember that i read about "whatever" sometime in google reader.

I'd like a searchable index, possibly title lists of the posts i've shared. This would be an awesome mental notebook feature, and most likely not super hard to implement.
