Self-explanatory. Does not seem to be possible so far. Would be great!
I would expand this to be able to search or filter on any field. So far as I can tell search looks only at name and slug - better than nothing but not brilliant in a 1000 item collection with 50 fields. The filter option is of very little use as it looks only at publishing dates and status. I work around it by pinning fields to the view and then sorting - but if the items I am looking for are anywhere but the first page, its irritating.
