I Google "site search" tested a bunch of small sites published this year. When I clicked through to the cached page I got, "Your search - cache:LVC4Sap71YQJ:www.(domain name).com.au/frequently_asked_questions site:(domain name).com.au - did not match any documents."
A number of these sites had been stripped back so that only their Home page remained indexed. All of the sites I tested were published by different companies - so no commonality factors were at play.
Doesn't this suggest Google is having problems with its index?
