To Whomever fixed the search and the broken cache - Congratulations
searching for config.php only returned two pages of results - to mid june.
Unfortunately I can only get two pages of results.
I click "more" once and then retrieved a second page of results. On the second page of results there was no "more" option and there were clearly more comments with "config.php" in it.
It would be great if their was a pager module in their as well as the possibility to get more results.
I may not provide the completed solution you might desire, but I do try to provide honest suggestions to help you solve your issue.
