This is an application for in house use   
Features over flash    
Happens to be a .NET WPF application  

Used to have structure UI pages for building up the search. Users told us they would rather have a WestLaw natural language syntax.  A SQL like language.  select * from documents where fName = 'bill' and date > 1/1/2002  

The crazy colors are sliders and those colors will change
