Google Custom Search not indexing Dynamic Pages

I am trying to use Google Custom Search to provide search capabilities to an informational site.

About the site:

• Content is generated dynamically
• URL Access to content is search engine friendly (i.e. site.com/Info/3/4/45)
• Sitemap (based on RSS feed) submitted and accepted by web master tools. It notes that no pages were indexed.
• Annotations sucessfully submitted based on the RSS feed

Problem:

There are no results for any keywords that appear on the pages that were submitted.

Questions:

• Why is Google not indexing the submitted pages?
• What could I be doing wrong?

From stackoverflow

• Custom Search with basic settings is principally same thing as standard search with site:your.website. Does standard search give you expected results?

  Note, that Google doesn't index pages immediately. It takes some time. Check if your site is already indexed.

• Yeah it took about 2 weeks for Google to pick up all my pages after I submitted a site map. But you should see a few pages indexed after a couple days.
