[jira] [Commented] (LUCENE-2987) QueryParser throwing null pointer
exception if input is invalid
[ https://issues.apache.org/jira/browse/LUCENE-2987?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13177427#comment-13177427 ]
Joe Cabrera commented on LUCENE-2987:
-------------------------------------
Currently the grammar accepts conjunctions AND and OR. Should it be expanded to accept lowercase and and or as well or should they return an explicit error?

> Key: LUCENE-2987
> URL: https://issues.apache.org/jira/browse/LUCENE-2987
> Project: Lucene - Java
> Issue Type: Bug
> Components: core/queryparser
> Affects Versions: 3.0.2
> Reporter: Ramesh
> Labels: newdev
>
> I was using org.apache.lucene.queryParser.QueryParser for parsing the input.
> My input:
> Input query string: "category: (4 or 6 or 8)"
> Analyzer: StandardAnalyzer
> QueryParser's parse() method is resulting in Null Pointer Exception.
> If i give input query string as "category: (4 OR 6 OR 8)" which is uppercase 'OR', it works fine and i get the desired results.
> I'm seeing the problem only with lower case 'or'
