Thank you, Dennis: https://issues.apache.org/jira/i#browse/LUCENE-5839
From: Dennis Walter [mailto:dennis.wal...@gmail.com] Sent: Sunday, July 20, 2014 2:52 PM To: dev@lucene.apache.org Subject: Bug in AnalyzingQueryParser Pattern Hi there, While reading the source code of AnalyzingQueryParser to understand what it does, I think I found a bug in the regular expression used to detect wildcards. It is defined as // gobble escaped chars or find a wildcard character private final Pattern wildcardPattern = Pattern.compile("(\\.)|([?*]+)")<file:///\\.)|([%3f*]+)%22)>; The first group will match a literal dot ("."), while its intention seems to be to match a backslash and a single character. So the expression should instead be "(\\\\.)|([?*]+)<file:///\\\.)|([%3f*]+)>" Best Regards Dennis
