This MWE: """ \setupinteraction[state=start] \setupregister[index][n=1] \starttext My \index{dog}dog is a \index{dog+bullterrier}bullterrier. He doesn't like \index{cat}cats. There are a lot of \index{cat+stray}stray cats, but only a few of them are \index{cat+Siamese}Siamese. I don’t think there are \index{cat+Burmese}Burmese cats. \seeindex{cat+obese}{cat+Siamese} \seeindex{hound}{dog} \completeindex \stoptext """ ... shows two problems at once: """ c cat 1 Burmese 1, see cat+Siamese Siamese 1 stray 1 d dog 1 bullterrier 1 h hound see dog """ While the reference "hound see dog" is properly formatted, cat+obese is missing (i.e. sorted under Burmese) while there is no \index{cat+obese}, and the reference "cat+Siamese" is shown as-is, not properly formatted. That means, refering to index sub-entries is broken at the moment (current beta and at least several previous).
