With older versions of ConTeXt (including that in TL18) seeindex entries pointing to a multi-level (plussed) index entry worked (visually, at least) without complaint. The output might look like: Digby, John 73 Dilbert see Adams+Scott Dirac, Paul 287 or Digby, John 73 Dilbert see Adams, Scott Dirac, Paul 287 where the second part is a literal repeat of what is in the second argument of seeindex. (It is not, however, linked to the plussed entry as it would be to a single-level entry.) However, current version (2018.07.27 19:12) generates a result like: Digby, John 73 Dilbert Dirac, Paul 287 along with the warning: structure > registers > invalid crosslink : Adams+Scott, ignored Surely it is better to display the non-linked see entry as before (together with the warning message so that the non-linking is pointed out) and have a printable document than it is to display an empty entry! -- Rik
