The search box in your instance is actually what I meant:

The difference between this and just searching for ‘World News’ is that if you do it this way, it will force your instance to index that instance if it hasn’t already done so. (You might get no results for a few moments after you click Search, only for it to then appear - that’s the delay while it’s indexed.) Obviously sh.itjust.works already knows about lemmy.ml, so it’s academic here, but when I made the suggestion, we didn’t know what instance they were looking for. :)
