XWIKI-9547: SOLR search suggest does not find pages which end with number or special characters
* Look in name_exact field also because the name field is analyzed and foo2013* doesn't return any results, probably because it is considered a phrase search and the wildcard cannot be applied to a phrase.
* Also wrap the __INPUT__ with round brackets (group syntax) to properly support multi-word search.
