I do missed this important article about index, which discussing about the focus concerns. In fact, I have used Composite Column to resolve my problem. In some context, data model can resolves as 'alternate index',  but it's complicated and can result new problems: data redundancy and maintenance. The most , what items I can query are decided at design time, that is, No Design No Query, even all data is there. Thanks to all.
