Have you submitted your SITEMAP? You need to submit your sitemap so that all your post will be indexed by Google. Anyway, if you have submitted your sitemap, please wait couple of days before Google will index all your contents.
But in your case, I think that you haven't submitted your sitemap, how to do that?
1. Look for sitemap generator
2. Go to your webmaster tool and test your sitemap, if it's working, submit it.
I know this is too general, please look for tutorials "how to submit sitemap to Google without errors"...
