Index options

Hi,

I would like to create several indexes in my PhD thesis. After thorough 
reading of section 2.11 of the User's Guide and some experiments, the 
following questions remain unanswered for me:

1) Which option do I need to set or change in order to change the title 
of Index A, rather than the main index? At p. 70, the User's Guide does 
not say any more than: "There are setup file options to change the 
titles of indexes." In which setup file can I find this option, when 
producing a book?

2) The User's Guide mentions at p. 70 that @IndexA can be renamed to, 
e.g., @AuthorIndex. Which are the implications of this on related 
symbols, i.e. will I have to rename @IndexABlanks to @AuthorIndexBlanks 
(and analogously for all further options) or will these symbols still 
work? Or is it just for the convenience of using a telling name when 
marking the terms to be indexed?

3) In the index entries, I don't want the comma to be printed before the 
first page number, as indexes in German typically don't use a comma 
here. It seems, however, that there is no option for changing this. What 
could I try to get this comma removed?

4) Being able to show (partial) synonymy between index entries would be 
great. All that is needed for this is a subentry with just a 
cross-reference instead of page ranges ("see also ..." before other 
subentries with page ranges, or "see ..." as the only subentry). To 
create them, I thought of putting something like this into my document:

basic @RawIndex
  { Basic, see also tagOfFundamental @CrossLink Fundamental}
...
basic.very @SubIndex { Very Basic }
...
fundamental @RawIndex
  { Fundamental }
...
fundamental.really @SubIndex { Really Fundamental}

The problem is, I am not sure how to have the tag tagOfFundamental 
inserted by Lout in the right place, i.e. where the index entry for 
"Fundamental" will be placed. How do you do this?

(Often or always, bidirectional cross-references for near-synonymy might 
be preferable, but I didn't show this above to keep the example simple, 
and adding the second target is technically trivial.)

Or do you know of a more clever approach for reflecting (partial) 
synonymy among index terms?


Can somebody help?
