Maybe you knew, maybe you didn't know, but probably we should all have guessed it: Facebook keeps a log of your search history--everything you type into in that "Search for people, places, and things" box at the top of Facebook. While this information is shown to you only, perhaps you'd like to see what's stored there and maybe clear that search history if you don't care for it.
Of course the setting is buried. Head to the gear icon at the top of the page, then Activity Log. In the left menu, click on "More" (under "Comments") to expand the menu. Then click on "Search."
You'll see a list, by date, of the searches you've made in Facebook. And, if you want, can click the "Clear searches" option at the top right of the page.
Now, this doesn't necessarily mean that your search data is actually deleted from Facebook's databases, because there's no information about that so far. And there's no obvious way to prevent your searches in Facebook from becoming part of your activity log.
Still, the setting and the history are there if you want to take a look.
