 >  - Using constants for field names makes sense, though "ascending" and
 "descending" don't really belong there but rather in the `server` package.
 Still, starting such a `Fields` interface or enum in the `docs` package
 sound fine.

 The asc/des-fields are used by the comparators and should be in their
 package, maybe in a different interface, e.g., Order.java or the
 comparator class itself?

 >  - Separate comparator class makes sense, though I'm not sure whether it
 rather belongs in the `server` package than `docs`.

 The comparator class is only concerned with docs, the server package uses
 docs and their comparators. Thus, the comparator class should be in docs.

 >  - Changes like copyright updates or Java 7 changes should be done in
 separate commits and for the entire code base.

 Separate commits for these changes true (that's why I didn't call my
 branch patch).
 Copyright can be done via commandline and for all classes at the same
 time, agreed.
 The java 7 changes require more fine-grained code changes and could also
 be done whenever classes are touched anyway.  So, it's more a question of
 available time to do these at once or class by class.

 making changes myself this afternoon and ask you to review them
 afterwards.  Up to you.  Thanks!

 Having other high priority tasks at the moment, I could sneak that in next
 week at some point, if you don't get to it.
