No one will ever see this (probably) but I remembered this comment, and just had this experience:

I've been learning the eBay developer APIs. Recently (i.e. within the past few hours) I looked up the "Browse API" specifically. My first or second try failed so I typed just [ebay brows] and didn't find it! But when I finished [ebay browse] that document (within ebay.com and titled "Browse API | eBay Develo...") did show up!

I can't reproduce now so I can only guess but it's possible this was a timing thing. I was typing several things, and changing/re-typing "as soon as" I did or did not see what I wanted to show up. But there was definitely a moment where I'd expect "that page I just had open an hour ago" to be at the top, but instead search suggestions (ugh, search in the address bar ...) were all that was showing.
