This is clean and green for me:

   public void testAbc() throws ParseException {
     Query query = QueryParser.parse("\"abc\"", "field", new 
     assertEquals("abc", query.toString("field"));

Either you're using an old version of Lucene that is broken in this 
regard (I'm at CVS HEAD) or something else is fishy.

Note that a single term in quotes is optimized into a TermQuery, not a 
quoted PhraseQuery in the assert above.

Ranges with spaces in them doesn't work.  It is for single term ranges, 
not phrases that were tokenized.  If you indexed the entire "phrase" as 
a single term (Field.Keyword), then you could do an API RangeQuery, but 
QueryParser won't be happy.

QueryParser syntax is documented on the Lucene website if you need 
assistance with the type of syntax it supports.
