Can Google be used for site search on a database backed website?

I'm developing开发者_如何学编程 a web site with Google App Engine, and I want to have a search feature for user submitted stuff. Since this project is just a toy and I don't control the server, I'd like to just use Google to handle search. However, since the content is stored in the database, I don't think Google can discover the dynamic urls. Unless maybe I create a page that links the last N submissions and hope it gets crawled frequently. Thoughts?

Absolutely. As long as the database is exposed in a web page which can be crawled, Google will crawl it (unless told not to).

The best way to make it all accessible is decent navigation between pages. However, lacking that, a site map page linked from the home page should suffice.

This is an excellent candidate for a sitemap.

You can generate the XML any way you want, and give it to Google. The best part is, it is a "private" XML file; no need to have ugly listings of dynamic URLs for users to see.
