Using sys.dm_db_missing_index_group_stats

Using sys.dm_db_missing_index_group_stats?returns summary information about groups of missing indexes, excluding spatial indexes. An example follows:

SELECT TOP 5 *  FROM sys.dm_db_missing_index_group_stats  ORDER BY avg_total_user_cost * avg_user_impact * (user_seeks + user_scans)

The above query determines which 5 missing indexes would produce the highest anticipated cumulative improvement.
