QueryParser removes "\" when searching in Persian
To be able to search in Persian, I convert the original query from a form field which is in the XML CharRefs formt, e.g. "ايران", to "\u0627\u064a\u0631\u0627\u0646". since all websites i am indexing are using XML CharRefs it makes it possible to search in Persian. but when making a Query from "\u0627\u064a\u0631\u0627\u0646", it seems that QueryParser removes all backslashes (\).
String qry = SomeExternalParser.parse("someQuery");
which will return : qry = "\u0627\u064a\u0631\u0627\u0646"
QueryParser queryParser = new QueryParser("fieldName", new StandardAnalyzer());
Query query = queryParser.parse(qry);
now query.toString() shows: [filedName]:"u0627u064au0631u0627u0646"
how can i prevent QueryParser doing this? i should mention that if i write the query as an String such as: String qry = "\u0627\u064a\u0631\u0627\u0646", then it works fine. but when i try to get the qry from another method or class, this strange behavior happens.
cheers, reza
