//TSSearchController.js - 20081002 - Emile van Raaij, Topshare International BV
//
// Implements a controller for formatting and handling search requests that
// works with a tag that leans on Topshare.SearchHandler
// NOTE: since the interface to the Lucene search is NOT uniform for tops and nodes- we encapsulate the knowledge of
// 			the field fill-in in this class... This needs to be fixed by a redesign!
