Hey Matt, This is issue 420: https://issues.apache.org/jira/browse/LUCENENET-420
I think the theory so far has been that the user should manage the culture rather than Lucene. If you disagree could you post on that issue ticket? Thanks, -Ben ----- Original Message ----- From: Matt Warren <mattd...@gmail.com> To: lucene-net-...@lucene.apache.org Cc: Sent: Thursday, June 30, 2011 9:28 AM Subject: [Lucene.Net] Possible bug in Lucene with Prefix Search and Danish Locale I think that the code here shows a bug in Lucene.NET, see http://gist.github.com/1056231. This happens when using 2.9.2. After some digging I think that it's due to the way it does a Prefix search. The main problem is shown by this code http://gist.github.com/1056242. If the Locale is Danish, this returns FALSE, weird eh!! "daab".StartsWith("da") //false But this works as expected "daab".StartsWith("da", StringComparison.InvariantCulture) //true The line of code that has this problem is the TermCompare(..) function in PrefixTermEnum.cs, see http://svn.apache.org/repos/asf/incubator/lucene.net/trunk/src/core/Search/PrefixTermEnum.cs
