Site search appears to work for www.mydomain.info, however I am not getting results for www.mydomain.info/123/. In other words, the top domain search is returning results for www.mydomain.info/index.html, but site search is not working for any content stored in the /123 sub-directory.

This page:Why do I not get any results for a SiteSearch on my domain? (https://www.google.com/support/adsense/bin/answer.py?answer=10526&topic=167) does not provide a solution.

Any ideas?

All pages have to be indexed by the regular googlebot in order to appear as search results for AdSense for search. If that particular directory is new, googlebot might not have indexed it yet.

Other things to consider: Have you checked that you aren't blocking googlebot via robots.txt or meta tags? Is there an issue with the webmaster guidelines as to why those pages aren't being indexed with Google?

If you do site:www.example.com with your own domain name, it will show what pages you have indexed, and those are the pages that will show as search results when you use AdSense for Search.
