The search engine Bing, likewise Google, too, lists Twitter posts and profiles within its search results, MediaPost Publications reports. For now this is limited to popular Twitter users, because of the Twitter limitation on using the api.

To find Twitter posts or profiles it is mentioned in the article to add the term “Tweet” to a search query. But Twitter entries do appear, too, by adding the term “Twitter”. So Tweets and profiles seem to be a regular part of the search engine index.
