Hrm, I don't think so. Maybe you could do this by adding your own
stemmer for Greek, but that would involve some low-level c++ hacking.

If you use the "mgpp" index instead of the "mg" index for the backend
then you can search on multiple metadata fields at once. We have an
example mgpp collection on the website:
or go to and click on the "Colt Bibliography" collection
in the "demonstration collections" section.
