This is a search engine I put together using a custom Google search. The standalone page is here, but I also created blog to serve as the gateway so that it would be easy for others to suggest new sites to index. To request that your site be added, please visit:
http://osrsearch.blogspot.com/
You can see a list of all sites indexed here:
http://osrsearch.blogspot.com/p/sites-indexed.html
Please check to see if your site or blog is already on the list. I have already preemptively added quite a few.
You can embed a specific search in a link by appending &q=searchterm to the URL of this search engine. For example:
http://www.google.com/cse?cx=015800199008943638690%3Ae6ufoimln7g&q=thief
