It shouldn't just be "foo OR bar" because he needs to search for objects
with *two* metadata rows associated with it: one set to foo, and the
other to bar. If we have four objects:
Object ID metadata (in CSV format)
1 foo
2 bar
3 foo,bar
4 baz
Your suggestion selects 1,2,3. He wants only 3 to be selected.
