Description

As explained by Paweł Róg on java-user [1], the output of parsing the queries below is different depending on the default operator. This looks odd and should be investigated.

QueryParser parser = new QueryParser("test", new WhitespaceAnalyzer());

    parser.setDefaultOperator(QueryParser.Operator.AND);
    Query query = parser.parse("foo AND bar OR baz ");
    System.out.println(query.toString());

    parser.setDefaultOperator(QueryParser.Operator.OR);
    query = parser.parse("foo AND bar OR baz ");
    System.out.println(query.toString());

Results in :

+test:foo test:bar test:baz
+test:foo +test:bar test:baz
