SOLR search suggest does not find pages which end with number or special characters

Steps to reproduce:

• make sure SOLR is the default search
• create a page called "foo2013" and save (Note that the title of the page will also be "foo2013")
• using the Search Suggest, try searching for it. If you search with "foo", you will have the pages suggested. But if you write "foo2013" (the full and exact page name), you will get "No Results !"
