Yes, I think nested queries are the only way to do that, and yes, nested
queries like Daniel's example work (I've done it myself). I haven't really
tried to get into understanding/demonstrating _exactly_ how the relevance ends
up working on the overall master query in such a situation, but it sort of
works.
(Just note that Daniel's example isn't quite right, I think you need double
quotes for the nested _query_, just check the wiki page/blog post on nested
queries).
Does eDismax handle parens for order of operation too? If so, eDismax is
probably the best/easiest solution, especially if you're trying to parse an
incoming query from some OTHER format and translate it to something that can be
sent to Solr, which is what I often do.
I haven't messed with eDismax myself yet. Does anyone know if there's any easy
(easy!) way to get eDismax in a Solr 1.4? Any easy way to compile an eDismax
query parser on it's own that works with Solr 1.4, and then just drop it into
your local lib/ for use with an existing Solr 1.4?

It may also be an option to mix the query parsers?
Something like this (not tested):
q={!lucene}field1:test OR field2:test2 _query_:{!dismax qf=fields}+my dismax
-bad
So you have the benefits of lucene and dismax parser

Betreff: Re: DismaxParser Query
What version of Solr are you using, and could you consider either 3x or
applying a patch to 1.4.1? Because eDismax (extended dismax) handles the
full Lucene query language and probably works here. See the Solr
JIRA 1553 at https://issues.apache.org/jira/browse/SOLR-1553
