Remarks

Search starts with firing SearchProgressing event. During search, Searched event will be fired if any match is found. SearchProgressing event is fired each time with Status 'Progressing' when the search finishes the current page and moves to next page. When search completed Searched event will be fired with Status 'Completed'. If user cancels the existing search through user interface or through code by invoking a new search, then Searched event will be fired with Status 'Canceled'. Change in the search term, options, search direction or invoking a new search when current search is progressing, will result in resetting of the current search.
