i fix it, the problem is that documentation is incomplete, please note in the documentation that to use query language we must use single line query

Documentation fix is required

I this is a legacy of the Tokenisation change in 3.5.
SingleLineTRECQuery uses the new Tokeniser.getTokeniser() method, which defaults to EnglishTokenizer (that does not keep query language characters).
tokeniser should be set to a tokeniser that supports the query language.
