Subject [jira] Commented: (LUCENE-995) Add open ended range query syntax to QueryParser
Date Wed, 10 Nov 2010 23:44:14 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-995?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12930840#action_12930840
] 

Masoud commented on LUCENE-995:
-------------------------------

Is this a fix just for the date fields, or does it work for all fields, for example will 
 Author:[* TO *]    work to get all Authors that have something in them  (and also, query
like  *:* -Author:[* TO *]   to get all records that are missing the Author field?)

Any idea what version of Lucene this will be included with and when it will be released?

> 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).
