Find Web Pages That Link to Documents, MP3s, Videos, ZIPs or other file types
The contains: operator in Bing Search helps you find web pages that link to other online documents and multimedia files like music and video. This is different from Google’s filetype: search operator (which is also available in Live Search) that looks for content inside PDF and Office documents.
For example, if you are looking to download a Microsoft Word report from MSDN site that is about SQL, just type: site:msdn.com contains:doc SQL
Similarly, if you like to find all pages on Wikipedia that link to MP3 files, type “site:wikipedia.org contains:mp3″
Get Bing Search Results as RSS Feeds
Neither Yahoo! nor Google provide RSS feeds of their search results.
You can subscribe to search pages from Bing as RSS feeds. Open Bing Search, type your query and then on the results page, append “&format=rss” to the URL. Or, you can just click on the lighted RSS icon in Internet Explorer.
This parameter converts the Bing Search page into an RSS feed that you can add to your news reader. You can also append &count=200 to increase the search results up to 200 items.
Limit Your Search to Websites that offer RSS Feeds
Another search operator in Bing Search is “hasfeed” - it lets you find only those web pages that link to RSS feeds. For example, you could write “ASP.NET MVC hasfeed:” to find web pages that are about “ASP.NET MVC” and also syndicate content as RSS feeds.
You can also group hasfeed: with other search operators so if want to know about all pages related to ASP.NET MVC on MSDN.COM that have feeds, just type “asp.net mvc site:msdn.com hasfeed:”
Use intitle: to restrict searches to results where the search term is in the page title.
You can use the "intitle:" directive to find only results where your search term appears in the page's title element. For example, to find pages where "ASP.NET" appears in the title of the page, you could type intitle:asp.net
Track Companies from the IE Favorites Bar
If you search for a company stock (e.g. GOOG or MSFT), Bing will automatically create a web slice for that company which you may then add to IE 8 and track the performance directly from the favorites bar. You need Internet Explorer 8 to try this feature.
