Adriano Crestani updated LUCENE-995:
------------------------------------
Attachment: LUCENE-995_09_21_2009.patch
The patch adds open ended range query to oal.queryParser.QueryParser. By
default it's disabled and may be enabled invoking
setEnableOpenEndedRangeQueries. I also added the capability to redefine the
open ended token, the default is '*'.
I also added some test cases.

>
> 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).
