Hi. #11378 doesn't talk about keeping the meta-data in the history generically. 
It mentions remembering the state for the last search, but you'd still have the 
issue in this bug for older searches. So unless I missed it (very possible 
since it was a very long thread), that bug doesn't touch on this. We can 
propose new things, however :)

I don't know how much complexity we want here. Each history item can be a 
richer structure than just the search string. Too much?
