The current Algolia search has made decent progress since it launched, but it's still not a decent enough replacement for hnsearch until proper filtering is implemented and a decent mobile version is out (Can't select any filters at all in the mobile version, and can't even switch to the desktop version). HNsearch.com is scheduled to be shutdown in a week, but I'd love to see it up for at least another month, as it's still the only place one can get a decent search on HN.
