Yesterday we finally implemented Advanced search features on MSExchange.org.
If you take a look at the search box at the top right of each page you will see that there is an advanced search link. Once you click on that you can search any section, for any keyword, and in any section of an article or tip. You can also search within the forums, within the white paper sections, etc. Everything is integrated.
You can also display results based on relevance, date, or title. This is something that many of you have been asking for a long time!
