Subject [jira] Commented: (LUCENE-950) IllegalArgumentException parsing "foo~1"
Date Mon, 11 Aug 2008 09:59:44 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-950?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12621400#action_12621400
] 

Eleanor Joslin commented on LUCENE-950:
---------------------------------------

Perhaps all that needs doing is to note on the javadoc of 
QueryParser.parse(String) that it can throw IllegalArgumentException as 
well as ParseException, so that consuming code can catch it.  An 
application shouldn't blow up just because a user types something silly 
in a search field.
