Well, I don't think this is done normally. I'm assuming here that
you've simplified the example and your *real* requirements aren't
quite what you're showing, because what you've described seems
really confusing to a user.

That said, I don't think SOLR has a way to handle this out-of-the-box.
What you're asking for is for the query to search different fields based
on the *results* of the parsing. You have to deal with someone searching
for "tests" OR "run", which presumably should return anything
with "test", "tests", "testing", "run". But should NOT return a doc
with only "running" in the title. But to the parser, this starts out as
title:(tests run)....

So, you really need to see the results of feeding any term through
the stemmer. If it comes back the same as what you fed in, go
against one field. If it comes back stemmed, go against a
different field.

You'll probably have to create a custom parser that pre-processes
each term and determines which field should be searched, search
the SOLR list as creating custom parsers has been discussed
before by people more knowledgeable than me...

If my assumption that there are parts of this problem that you've
simplified is NOT correct, perhaps you could explain the use-case
that leads to this requirement....

But if anyone has a better idea, now's the time to speak up <G>.

Best
Erick
