For both the Missing and Unused index tools it is good to remember that these are recommendations. The best tool is properly tuned squishware (that part of the system that exists between your ears).

How many programmers does it take to change a light bulb? None; It's a hardware problem.
How many therapists does it take to change a light bulb. None; The light bulb must change on its own. The therapist is only a guide.

Likewise the missing index tool is a guide.

Would someone kindly elaborate on sys.dm_db_missing_index_group_stats
column user_scans. I tried all kinds of good and bad things in queries to bump user_scans in statistics and it doesnt budge. WHat will cause it to be non-zero?

Hi,

Nice article.

You can discover a lot more about DMVs in this forthcoming book www.manning.com/stirk. Chapter 1 can be downloaded for free and includes scripts for:

A simple monitor
Finding your slowest queries
Find your missing indexes
Identifying what SQL is running now
Quickly find a cached plan

Thanks
Ian

I have found this feature very helpful but could be improved, I would even call it buggy:

- As Microsoft mentions, it does not consider trivial Plans. Why not? A trivial index from a trivial query on a huge table is missing - I'd like to know about it!
- Actually recomended a few indexes that already existed!
