Best/easiest practice for filtering search results using c#, asp.net and RDF database?

I'm hoping to get your input on this. If you have experience doing this work, please share your knowledge!

I am currently following this article using filter.js and json objects for filtering results. I've been playing with this for several hours now, and although his demo looks great and is what I'm looking for, there is a big learning curve for me and I'm teaching myself right now. It requires quite a bit of jQuery manipulation/customization but I don't know a whole lot about jQuery, and I'm hoping someone can point out the right direction for me to start. (Such as tutorials). I've also looked at this article already. I need to develop a search filtering tool that upon displaying all search results (the default view is all records) will allow the user to filter these results by checking and unchecking boxes -- think online retail stores like Amazon or Best Buy. There will be about 250-500 records to filter through. The results will have attributes such as, Title, Description, and a link to view more about that record.

The filtering must be performed on the client side, no postbacks/refreshing, for best results. I've looked into update panels and repeaters, however, my biggest learning curve is currently jQuery and I am unsure to figure out which is best practice and how to start.

EDIT: I should also add that I'm new to the RDF database as well. I've only had SQL experience.
