// What the warranty list's search box matches against.
//
// Pulled out of WarrantiesList.vue so the field list is somewhere a test can
// see it. It went wrong the way a field list usually does: silently, by a
// column being added to the table and not to the filter.
//
// THE MACHINE NUMBER IS THE POINT. _related_machine in the warranty API exists
// precisely because "a shopfloor PC is bought, warranted and replaced as a PC,
// but it is FOUND by the machine it drives - nobody walks the floor looking for
// an asset number". The payload carries it, the table renders it in a chip, and
// the filter did not look at it - so the one identifier the feature was built
// around was the one thing the search box could not find.
