I do not see it and I am checking on terms that currently show sitelinks.

-Edit- I finally got to see it on a specific search I did. It certainly is limited to a few domains (e.g. Microsoft). It's a big mystery to me how and why sitelinks appeared for some domains in the first place, and now this search box has appeared.

Thanks for the info.
