we already have this finctionality - fielded search is available if you
build your collection with MG++ instead of MG (the default). see
http://nzdl2.cs.waikato.ac.nz/cgi-bin/library?a=d&c=gsdldocs&cl=CL1.2&d=HASHb60c1d76b91cacaba1f2d3

for some details.

For these collections you can select form-based search from the
preferences page, which provides fielded searching.

cheers,
