thankyou Vianney and Jano,
I'm using MarkII.
Anyway \pagenumber is not usefull because there ir more than 1 index item per page.
But using a number and incrementing it each index ocurrence works neither.
Excuse my ignorance, but I don't know what is "expanded" or what does the "expansion" key?

thankyou for your answers.
