You recently upgraded a SharePoint Server 2007 server farm to SharePoint Server 2013.
You discover that when search results contain Microsoft Word 2007 documents, the results do not display the title of the documents. Instead, the results display a few words from the text of the documents as the title.
You need to ensure that the title of the Word 2007 documents is displayed in the search results.
The solution must minimize administrative effort.
What should you do?
