    I am not sure whether here is a right place to ask.  Do you have any good references on Indexing(clustered and non-clustered index) , what is supposed be called best index structure?  I have read through MSDN article on this topic. From my understanding, basically index should be add on the table column that is frequently use for searching data(not searching for the exact: where non-clustered will do better job) in order to get a better performance result) however I would like to ask can you provide any other good references to read that help me to understand it more?
    Thank  you.

    Yes... might as well get it from the master herself.  Do the following search.  Any of the videos with "(MCM)" as a part of the link title are totally awesome.
