      It's important to realize that the same Image can be in more
      than one category. This gives you much more flexibility in
      searching and categorizing your objects than you get with a
      FieldIndex. Using a FieldIndex your portrait of Queen Victoria
      can only be categorized one way.  Using a KeywordIndex it can be
      categorized a couple different ways.

         problem: you can retreive all the records if you leave keywords blank (eg searching also with other indexes
         and not choose any keyword)
