ORDER BY using index, tsearch2 [READ THIS!]

[Sorry, this previous mail was HTML-foramted]

Hi,
 
How can I use this ORDER BY using index feature presented in this implementation.
It doesn't seem to be in use, when I have a look in my query plan.
It still does an cost intensive Bitmap Heap Scan and a Bitmap Index scan.
I also can't find the "><" operator in any introduction of the tsearch2 extension.
Is it just an idea?
 
Thanks for your help!
