To start, I recommend you review the Model-View-Controller section of Cocoa Core Competencies.
Within that framework, table views are… well… views. As such, they are a view on to your model data, not the data itself. If you want to search your data, you wouldn’t search the table view, you’d search the model that the table view is showing.
