Other indexes

Hi,

I am a new user of mhonarc I found it very fexible and intend to replace my
current hypermail.
But I have a problem with "otherindexes".
I cannot have at the same time AUTHOR, SUBJECT, DATE indexes.
When I use "otherindexes" I can only get one at a time.

What did I do wrong ? Help.

Thanks in advance.
