Google Index Problem
If you wait for 1 or 2 days to your pages to Catched in google . To come indexed by Google Bot, but still your posts will not appear in the Goolge Blog Search API.
I have verified all my 50 pages indexed by Google bot and for all pages in the Catche link are available but the Catche page is missing. I think it is because of assuming that Blogger has already stored the page but since the blogger failed to index our pages the Catche pages are not available.
The same issue was found in many threads and they even provided the links to their posts. I could see that some of their pages are indexed by Google Bot after they reported the issue, but the Catche page is not available for these pages.
I Tryd the time line search “Last 24hours” option in Google using the search string “anykeyword site:blogspot.com” and verified many blogs and found that there are many blogs have the affected by this issue, but not all.
Those who want to verify weather your posts are indexed by Blogger internal Bot or not they can visit the AJAX PLAYGROUND at http://code.google.com/apis/ajax/playground/?exp=search
and see weather your new posts are being fetched by the Blogger Search API.
Only Google Employees can answer why Blogger Stopped indexing the posts instantly since 19-Oct-2010 for many blogs.
