One way to do this is with a stub database.  This example is stolen from 
an email asking for help.

Databases:
/var/lib/xapian-omega/data/db1
/var/lib/xapian-omega/data/db2
/var/lib/xapian-omega/data/db3

Stub:
/var/lib/xapian-omega/data/default

The stub file "default" is a text file that contains the following:
auto /var/lib/xapian-omega/data/db1
auto /var/lib/xapian-omega/data/db2
auto /var/lib/xapian-omega/data/db3


/usr/lib/cgi-bin/omega/omega 'DB=default' 'P=searchphrase' 'FMT=xml'

The file doesn't have to be named default.

Hope that helps,
Jim.
