the point of Alexander is that, according to MARC standard, 024 contains a DOI
if and only if there is the string "DOI" in $2. Otherwise it could be a
different persistent identifier.
Currently Invenio can not index subfield values in separate indexes according
to the string existing in an other subfield.
Cheers!

P.s. this is currently a non-issue for INSPIRE for the time being (since you
store only DOIs in 024), but is a needed functionality in Invenio.
