My site has hundreds of pages. when is do a site: search in google it comes up with more than 200+ pages but when I do the same search in yahoo it comes up with just one page (homepage) and bing comes up with 4 pages including home page.

I have submitted the xml sitemap in all the search engines about couple of months ago.

I write couple of articles everyday on my site and they usually get indexed by google within minutes but the problem is with the other two

How can I get the rest of my pages indexed in yahoo and bing?

Thanks
