Soleimanian,
Your site is currently ranking very low. I believe the first step to increasing your rank is to canonicalize your site. If you are not familiar with canonicalization, I suggest reading some of the recent posts on our webmaster blog located at:
http://blogs.msdn.com/webmaster Many of the posts have great information that can help you rank higher and increase indexing. I also suggest reading our FAQs located at the top of the Indexing and Ranking forums as they can provide a better understanding about how our crawler works.
Good Luck!
