       | Since there's no tagging, maybe a specially crafted search result
       | 
       | ie. (NASA, JAXA, IRSO, moon, satellite, space, telescope, hubble,

         | There is hn.algolia.com which can be used to (kind of, at
         | least) achieve that but it's not a perfect fit.
         | 
         | This is a result if you search "JAXA" and sort by All for the
         | Last Year so it's just _kinda_ there
