      #~ Qt::MatchContains	1	The search term is contained in the item.
      #~ Qt::MatchStartsWith	2	The search term matches the start of the item.

      #~ Qt::MatchWildcard	5	Performs string-based matching using a string with wildcards as the search term.
      #~ Qt::MatchWrap	32	Perform a search that wraps around, so that when the search reaches the last item in the model, it begins again at the first item and continues until all items have been examined.
