First... I know NOTHING about google API, or how it works etc., but do have an API key. What I am wanting to do is to be able to download, or see in text format the search results for a Site: search. I changed my site from .cfm extensions to .php extensions and need to redirect all pages that google has indexed to the new pages, and think it would be easier to do if I was able to get the Site: results in a .csv file or something. thanks
Those will likely start over as new pages, you may be able to use .htaccess to pass files with a cfm extension through the php interpreter in order to keep your filenames. This may save you from 'starting over' with Google. If so, place the following code into your htaccess file AddType application/x-httpd-php cfm AddHandler application/x-httpd-php .cfm
To download search results u have to use a script. It may be in php, perl, java, tcl or vb. You can search phpclasses site for php script to download google search results using google API.
Just convert the cfm extension to php in the .access file like maxpowers states, this will allow you to phase in and phase out the pages with google being directed to the new pages without noticing the change, really.
