Custom Search using new View Object (Programatically)

Question

Hi Experts,
Currently i am exploring the ADF-BC and i have a basic question. Hope you experts will help on this. I am thinking of implementing the search functionality with out using the "Query component" because the search that i am going to implement is complex and very custom. So for that i have decided to create one View object with the controls that needs to be displayed in the search screen. E.g assume the DepartmentVO is available and i want to create the search screen So i have create a another view object called DepartmentSearchVO (Program view object) and create transient variables for each search filed that i was thinking to have.
Now i want to implement the Search button. When the users clicks on the search then i can called the DepartmentVORowImpl method called search() and construct the query based on the input. Then how about the results return. Since the DeparmentVO is coarse grain i am thinking to have another light View object called DeparmentLightVO (Program object) and use that to bind with the table for display.
Please let me know am i going in the right direction. Is there any better way for this kind of requirement implementation.

Hi,
As Shay mentioned, you could set the where clause of the VO which you want to filter.
In your search() method, you could get the VO (DeparmentVO in your case), set the where clause based on the parameters you are passing to this method (or the columns in the DepartmentSearchVO) and execute the query.
You could use the VO (on which you've performed executeQuery) as a table / ROT in your application.
