[O] Control the entries of the index in org-mode exporting

[twiki]

I have a document in Org and I would like to add 
an index exporting to LaTeX, I would like to control 
the formatting of the entries in the index 
as is done in LaTeX with the command \index, e.g. 

\index{Actors!Jack Nicholson} 

Any suggestions? 
THANKS
