Custom column in BP Search Result view

Hi,

I have to create a custom column in BP Search result view for that I appended the structure CRMST_HEADER_OBJECT_BUIL with a field. I did the required configuration to have this displayed in BP Search result view.

I am not sure where to code to get this field populated. Please help me with the method/class in which I need to code to fill this new field.

Thanks,
Chandu
