Due to the way that the server behavior is created for the DataAssist Search it is difficult to determine how the search is setup based on the code in the pages. If you can please explain a little about how you would like this to work, how you have setup the server behavior, and what you expect for the result. I know that it may be a very basic setup to you but each case is going to be a little different so it is very difficult to say what you may need to change or do differently to get the correct result without knowing a little more about how you have it setup and how it should behave. An example search and the desired result would be very helpful as well.
