MLT in SolrJ vs. URL?

[Darren Govoni]

Hi,
  I compose a mlt query in a URL and get the queried result back and a
list of  documents in the "moreLikeThis" section in my browser.

When I try to execute the same query in SolrJ setting the same params, I
only get the queried result document back and no MLT docs.

What's the trick here?

thanks,
Darren
