[jira] Commented: (LUCENE-588) Escaped wildcard character in
wildcard term not handled correctly
[ https://issues.apache.org/jira/browse/LUCENE-588?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12552434 ]
Terry Yang commented on LUCENE-588:
-----------------------------------
I wrote my first patch to this issue. if QueryParser knows the query is wildcard, it will directly pass the original query string to WildcardQuery which knows exactly which character is wildcard or not. i copied part of discardEscapeChar method from QueryParser because discardEscapeChar will throw ParseException which will causes WildcardQuery changed much. i am looking for a help/idea about what is the better way to process this exception?

> Environment: Windows XP SP2

> If an escaped wildcard character is specified in a wildcard query, it is treated as a wildcard instead of a literal.
> e.g., t\??t is converted by the QueryParser to t??t - the escape character is discarded.
