Last week at TechCrunch Disrupt, Mark Zuckerberg let loose that Facebook would create a search engine "at some point," and today the firm snuck in a smidgen of emphasis on queries into the Activity Log. Over the coming weeks, your searches on the social network will appear alongside the links, comments and other actions that are normally aggregated in the feature. Worried that friends will learn of your quest to find My Little Pony pages? There's nothing to fear as the log is for your eyes only. However, if a particular search blemish needs to be scrubbed from the list, each entry can be individually nixed like posts on a Timeline.
