Ready made insite search for asp.net website

Question

I have developed a business index which combines ecommerce websites.(in asp.net2.0+c#)

I'm looking for an in-site search engine that already handles issues like indexing, speed and quality.

Are there any famous solutions doing such?

I need the search results to be customized on my design, so google search engine isn't an option.

Thanks, Eytan
