John:
I'm not objecting to the XML, but to the very presence of "more than
one query in a request handler". Request handlers don't have, AFAIK,
"query chains". They have a list of defaults for the _single_ query
being sent at a time to that handler. So having
<str name="Query1"> blah blah </str>
is something I've never seen before, thus my weaseling that it may be
functionality that's new ;).
And also, AFAIK, there's no real sense of query chaining except
for the Rerank stuff.
That said, if you do want to use the results of one query in another
you can just put the whole thing into an fq clause (perhaps with
{!cache=false}. At that point you'd get back the top N does
that made it through the fq clause in score order.
Best,
Erick
