//Based on my other reader search script: http://userscripts.org/scripts/show/5958
//Directions for setting up the script with a custom search engine from:
//http://googlesystem.blogspot.com/2006/12/script-for-google-reader-search.html
// Go to your custom search engine at google.com/coop/cse . Do a search for test.
// You will get a URL like:
