this may be an interaction with the surrounding search-list. Not knowing
whether there is one, this is just a guess, but maybe you can try to
replace the search-region with a loop search, as it does not look as if you
would need the search region extensions for your index anyway.

you would do
[loop search="ra=yes/di=category"]
[loop-change category]
[condition][loop-field category][/condition]
your link goes here
[/loop-change category]
[/loop]

maybe my thinking is off, but I have not used nested searches, this may not
change a thing, but it's worth a try.

BTW: considering you want just the index, it may be worth creating the
index for inclusion via an export piped through a simple perl script that
generates the necessary tag stuff around the category field. This would be
done only after a change to the database, so you would not start a full
search all the time. Minivend is fast, but having it create the same thing
over and over again seems like a decidedly microsoftian way of doing things.

(Unless the database changes a lot of course)

cheers, frank
