Description of problem:
When searching for a (sub)string contained in a package's name by means of the HTML form on the top right of http://koji.fedoraproject.org/, it should be made clear to the user that this kind of search won't show any but exact matches.


How reproducible:
Whenever searching for a substring, instead of a package's complete name, on the aforementioned website.


Steps to Reproduce:
1. Visit http://koji.fedoraproject.org/
2. Feed a search term contained in your favourite package's name into the form
3. Perform the search
  
Actual results:
(Premise: Searching for the string "intel", without quotes)
The results page displays 'Search Results for packages matching "intel"', and "No search results" after that.


Expected results:
The system should at the very least make it clear that it was searching for exact matches only, and that wildcards ("*") are expected and can/should be used to do a somewhat more fuzzy kind of search. It might be worthwhile automatically initiating a search for "*intel*" if the application determined that there were no results found, and indicating that the scope of the search was therefore widened.
