Michael McCandless commented on LUCENE-995:
-------------------------------------------
OK I see what's causing the test failure ... the 3.x QP has separate code for
the inclusive vs exclusive range cases (in trunk they were merged at some point
I guess...), so, I'll fix the patch to also fix the exclusive case.
I'll also sync up QueryParser.jj so that when gen'd it matches the
QueryParser.java from the patch.

> The QueryParser fails to generate open ended range queries.
> Parsing e.g. "date:[1990 TO *]" gives zero results,
> but
> ConstantRangeQuery("date","1990",null,true,true)
> does produce the expected results.
> "date:[* TO 1990]" gives the same results as
> ConstantRangeQuery("date",null,"1990",true,true).
