(protected) new SearchRequest()
The SearchRequest object is created when searching a document. It triggers events to indicate search progress and it has properties to get the search results and status.
This constructor should not be used directly. Instead, a search request is created by PCCViewer.ViewerControl#search, and it is also made available through the PCCViewer.EventType.SearchPerformed event.
Example
// A SearchRequest object is created by and returned from the call to the search method
var serachRequest = viewerControl.search("FooBar");
