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.
