What to make of that?

Google search has a kind of spell checking function that gives suggestions based on what you type into the search box.

the Google bots pretty much follow the ukases of the robots.txt protocols. YMMV.

Search engine companies use software bots (from 'bots from robots), aka spiders, to crawl around the web indexing everything they can. The admin of a website can place a text file called robots.txt with some rules in it about which directories and files on the website hosting computer may or may not be indexed. (YMMV == your mileage may vary.)

Ceci n'est pas un seing.
