SOLR complex queries misunderstanding

[Norgorn <ls...@mail.ru>]

I'm trying to implement specifying queries - we have some results and need to
search over them.
But query, I constructed, returns some strange results. 

q=(text:(specific) OR title:(specific)) AND (text:(first long query) OR
title:(first long query))

This query returns something, which contains "specific", but not  "first
long query", but result differs a lot from simple "q=(text:(specific) OR
title:(specific))".

I tried the following with same results:
q=(text:(specific) OR title:(specific)) +(text:(first long query) OR
title:(first long query))
q=(text:(specific) OR title:(specific)) AND _query_:"(text:(first long
query) OR title:(first long query))"

I'm sure, that this is the real query, going to SOLR, cause I checked it
before sending (SolrQuery.toString())

I can't find out what exactly am I misunderstanding (and what results am I
getting - they are really strange).

Hello Nick,

First of all, if you don't understand the results ask Solr to explain by
debugQuery=true. The output is reeeeaally verbose and puzzling. That is.
Then, I guess you tries to implement something like 'refinement', filtering
aka faceted navigation. Try to supply the filtering clause via fq=.. .
Filter queries don't influence scoring. eg fq=(text:(specific) OR
title:(specific))&q=(text:(first long query) OR
title:(first long query))
If I get your question right, you are puzzled by the
weighting/normalization, which works pretty puzzling for multiple clauses
queries with deep nesting. That is.
