I'm guessing that by "TL" and "TP" you mean "Teaching Language" and
"Teachpack".  The index entries are *not* divided onto these -- this
thing is working from the plain index nothing more and nothing less.
I don't see any reason to add any kind of specialization for the
teaching languages and teachpacks -- since the same issues are
relevant in all other languages too.

It is the responsibility of teaching language to generate a query that
will narrow down the full index to the relevant index -- and this
should be done by a "context query".  There are search operators that
make it possible to write a query that shows only entries from some
manual or that are provided from some module -- but in your suggested
organization you do hit the two big problems that I mentioned many
times now: you're describing a query that uses `or', and you're
describing a query that changes the order of results.
