how to transport portal index

Hi All,

I have question about transport portal index.

For transport portal content (e.g. iview, page, workset, role) could transport via

System admin> System configuration> Transport> Export or Import right!

But I wonder how can I transport index (web index) to my productive environment because my development and productive use deferent TREX.

Many thanks for all suggest.

Regards,
