Well, this is a start, but it's only part of the solution. What this will
do is ensure that only the canonical server name, b.com in this example,
is used for entries in the database. However...

This is tricker, as what you want is for a given, presumably static
database for all domains, to alter the search results' domain names to
match the domain name used in the URL that called htsearch. I think this
would require a combination of server_aliases as above for canonicalising
the domain name, and url_part_aliases to encode the canonical domain in
the database. Then, the search wrapper would figure out the domain name
used in the CGI URL, and pass that to the real htsearch which would use
it in its own url_part_aliases to decode the encoded canonical domain
into the desired domain name.
For example, in htdig and htmerge's htdig.conf:
server_aliases: www.a.com:80=www.real.com:80 \
www.b.com:80=www.real.com:80
url_part_aliases: www.real.com *site
Then in htsearch's config file:
url_part_aliases: ${searchdomain} *site
searchdomain: www.real.com
allow_in_form: searchdomain
Then, the search form would set the "config" input parameter to set this
particular search config file, and set the action to call a wrapper script
like this one, using the "GET" method:
-------------------------
#!/bin/sh
case "$QUERY_STRING" in
*searchdomain=*) ;; # searchdomain is already set, so leave it
*) # set searchdomain to HTTP host name used in request
QUERY_STRING="${QUERY_STRING}&searchdomain=$HTTP_HOST"
export QUERY_STRING
;;
esac
exec /some/path/to/real/htsearch
-------------------------
I'm pretty sure this should work, because htsearch seems to parse
allow_in_form's value, and make its input parameters override the
corresponding config attributes, before the url_part_aliases value is
parsed by the HtURLCodec class.
