How can I get \seeindex to refer to other than the
top-level of an index entry? In the following MWE, I would like to
link to text+more, not text, and not text+some.
That is, the highlight should include the name of the lower
level(s). The actual link should be to the page with the entry for
the reference text in the case that the top level is on one page of
the index and the secondary entry on the next page.
If this cannot be done, I can live with a separate \index{text,
more} entry, but that is ugly when there are other text+something
entries.
I would also like to be able to specify the format of the reference,
perhaps with before/middle/after keys. This would allow text
-> more or otherwise as my publisher's style guide may
require.
\setupinteraction[state=start]
\starttext
Some
text\index{text+some}.
More
text\index{text+more}.
And
more\seeindex{I want}{text+more} and more\seeindex{I
get}{text}.
