I would gladly wait hours or days for certain long-tail searches; the kind that I revisit every few days/weeks/months for half an hour trying various search terms to see if I can crack the code and find the content that I know is out there somewhere. I imagine getting status updates with intermediate search results, and I annotate each one with 'warm' or 'cold' and maybe add some more search terms into the hopper to forcibly narrow or expand the search.
