I am looking for a way to use l2s to return ranked result based on keywords.

I would like to take a keyword and be able to search the table for that keyword using .contains(). The trick that I haven't been able to figure out is how to get a count of how many times that keyqord appears, and then .OrderByDescending() based on that count.

So if i had some thing like:

string keyword = "SomeKeyword";

IQueryable<Article> searchResults = from a in GenesisRepository.Article
                                    where a.Body.Contains(keyword)
                                    select a;

What is the best way to order searchResults based on the number of times keyword appears in a.Body?

Thanks for any help.

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More

Ran into an odd behavior today with a many to many mapping of one of my tables in LINQ to SQL.
