Building an index not referring to page numbers

[wolf]

Hi all

I'm need to create an name index that refers to a specific heading and not to the page number. Our document is basically a collection of historical texts. In each text there are a few names that need to be indexed at the end.

So far I have used this field code:

{XE ”Name” \t “No. 001”} for each name. "No. 001" being the text number.

This works ok, but when a name occurs in two texts, the index doesn't sort properly.

E.g. the name occurs in text 2 and 3 the index will be:

"Name.....................No. 003, No. 002"

obviously I want this to be

"Name.....................No. 002, No. 003"

Any ideas on how to fix this?
