Are Search Engines Blocked from Indexing Forum Content?

Referring mainly to Google, I tried this:
Aeioun +Iraq

and do not get any hits for upstateforums.com
with numerous post containing both.

No search engines/spiders are blocked here. There appears to be 13,800 references to posts here on Google, but we have 30,000+ posts. Matter of fact, I actually supply a sitemap for google for all the posts here. How Google goes about indexing content is only known by Google but it appears for the most part, they simply grab the meta information, which is the same for every post.

Google only shows 230 references to Iraq on UFSC. Many of those don't even point to the specific post, but rather the forum index.

Google and other search engines do seem to have a hard time with dynanically generated content. They do a much better job with static webpages.

I will look into how I might improve search engines' ability to spider content here...
