Luis Alves commented on LUCENE-995:
-----------------------------------
I propose to improve the syntax to allow the following
"date>1990"
"date<1990"
"date=1990"
"date>=1990"
"date<=1990"
What do you guys think?
We probably could do it at same time we implement LUCENE-1823
> Add open ended range query syntax to QueryParser
> ------------------------------------------------
>
> Key: LUCENE-995
> URL: https://issues.apache.org/jira/browse/LUCENE-995
> Project: Lucene - Java
> Issue Type: Improvement
> Components: QueryParser
> Affects Versions: 1.9, 2.0.0, 2.1, 2.2
> Reporter: Jonas Gorski
> Priority: Minor
>
> 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).
