   There is no simple way :(

   You need to init a dictionary, run through the combined results and put
results into a dictionary, using URL as a key. Dictionary will
automatically cope with duplicate keys (URLs).

   But some duplicates still will be there. For example, a call to a Folder
(http://my.site/XYFolder/) will actually render its index_html. Now see:
the URL http://my.site/XYFolder/index_html is different... but the rendered
object is the same. So URL is not the best dictionary key. May be object's
absolute_url() or such.

   Anyway it is not simple and I recommend you to ignore dup results in
your OR searches. This makes the life (of programmer) much simpler :)
