Essentially this is possible but needs someone to create a suitable
context set for searching Marc.
A strawman for such a context set might be
So a query might look like
marc.245 =/marc.subfield="a" "Smith"
marc.300 = "*videocassette*"
(that does of course not include the necessary for indicators, leaders
and fixed field, but I'm not sure what the "necessary" would look like)
Others may have other views on whether the above is the best approach.
