Microsoft SQL Server Search Engine using Google co-op

Google has recently launched a beta service called Google co-op. According their overview:

Using it you can create a highly specialized Custom Search Engine that reflects your knowledge and interests.

Since it seemed to be a good idea, I gave it a try and created a customised search engine for specialised content on Microsoft SQL Server. This search engine allows you to use the power and knowledge of Google and refine the results of your queries, according additional keywords, giving a higher weight to those sites you consider to be more interesting, in order to return more precise results. In summary, all I have done is customise the search engine with websites related to SQL Server (Microsoft, blogs, usenet groups and so on). Feel free to give it a try and suggest me more sites to include to refine the searches further. It seems to work fine.
