See + <citerefentry><refentrytitle>systemd.journal-fields</refentrytitle><manvolnum>7</manvolnum></citerefentry> + for a list of well-known fields. If multiple matches are + specified matching different fields, the log entries are + filtered by both, i.e. the resulting output will show only + entries matching all the specified matches of this kind.

In general, a device node is the best proxy for + an actual device, as log entries do not usually contain fields that + identify an actual device. For the resulting log entries to be correct + for the actual device, the relevant parts of the environment at the time + the entry was logged, in particular the actual device corresponding to + the device node, must have been the same as those at the time of the + query.
