[ http://issues.apache.org/jira/browse/LUCENE-372?page=comments#action_12445343 ] Andreas Neumann commented on LUCENE-372: ----------------------------------------
The reason for this is that the parse() method does not ensure that the entire input string has been consumed. Query() will simply return if it encounters an unexpected token, relying on its caller to consume that token. If the query is nested, the call will throw an exception. But at the top-level, the caller is parse(), and it does not make sure that <EOF> is reached. A simple fix is to introdice a new nonterminal TopLevelQuery ::= Query <EOF>, and parse() calls TopLevelQuery. I have a patch for this, will post it together with a few new unit test cases for this.
