If I go to stackexchange.com and click all sites and list as names https://stackexchange.com/sites?view=list#name and then use my chrome browser to search for instances of "teach" I get 19 results.
However when I use the little down-arrow in my browser search, it takes me through the list on a bumpy ride, jumping (seemingly) randomly up and down the long page.
As far as I can tell there are only 19 instances and probably it's catching them all, just not in the sequence in which they appear in this sorting.
I've never seen this behavior before. Is it just me and my laptop or do other people see this as well? I don't think this is a bug, or a feature, perhaps just a curiosity?
