Yeah, it'd be nice if Query could be serialized across the wire and
could be deserialized in a new QParser on the Solr side. An
alternative to that is to use Lucene contrib's XML query parser.
Still a work in progress, but the basics are here: http://issues.apache.org/jira/browse/SOLR-839

That was exactly my point, Reza. As long as the query objects being
used are
"simple", there is no harm in using toString. But Erik's waring is
valid as
well.
Putting it in SolrJ would not make sense as the behavior of toString
is not
consistent. Query objects like SpanQuery don't even have a toString
representation.
Having said that, IMO users of SolrJ can take a consious decision of
using
Lucene to compose their query and do a toString for using SolrJ.

I found out that toString() works well as long as you use string
values and
do not use Lucene utility classes like
NumberTools.longToString(someLongValue)
Maybe nice future to have a Lucene query wrapper in solr package!

That is not what I'm looking for because my Lucene query is very
complicated and contains many Query sub classes.
org.apache.lucene.search.Query luceneQuery = buildLuceneQuery(); //
contains many types BooleanQuery, TermQuery etc
SolrServer server = new CommonsHttpSolrServer("http://example.com/solr
");
server.query(luceneQuery) // doesn't compile
SolrQuery solrQuery = new SolrQuery(luceneQuery.toString()); //
doesn't
work because toString() results to something like this:
+(stage:0000000000li84 stage:0000000000li74 stage:0000000000li76
stage:0000000009j1b7) -available_fields_field:*|DEACTIVATION_DATE|*

One little question: is there any utility that can convert core
Lucene
query
(any type e.q. TermQuery etc) to solr query? It's is really a
lot of
work
for me to rewrite existing code.
Solr internal APIs take Lucene query types.
I guess perhaps you mean transforming a Lucene query into a
parameter
for the external HTTP API?
new TermQuery(new Term("foo","bar"))
would be transformed to
q=foo:bar
