You could index both a compound field and the components separately.
This could be simplified by sending the value in once as the compound format:
  review,1 Jan 2007
  revision, 2 Jan 200
And then use a copyField with a regex tokenizer to extract and index
the date into a separate field.  You could index the type separately
via the same mechanism.
