SharePoint 2010: Limit search to return a Document Set after matching on its child item

Question

In SharePoint Server 2010, say I set up a Document Set and put some Word documents in it. Each Word document contains a common phrase that is found only in the body of the Word Documents.

When searching for this common phrase that exists in each of the Word Documents, is there a way to return only the Document Set in the search results, instead of returning each individual Word document?
