Description

At first I thought it's by design but Uwe says it's a bug. SQP emits this:

StandardQueryParser qp = new StandardQueryParser();
qp.setDefaultOperator(Operator.AND);
   
System.out.println(qp.parse("summary:foo", "deffld"));
System.out.println(qp.parse("-summary:foo", "deffld"));
System.out.println(qp.parse("!summary:foo", "deffld"));
System.out.println(qp.parse("NOT summary:foo", "deffld"));

summary:foo
summary:foo
summary:foo
summary:foo
