Subject [jira] [Commented] (LUCENENET-500) Lucene fails to run in medium trust ASP.NET Application
Date Wed, 20 Feb 2013 21:59:13 GMT


Joe Audette commented on LUCENENET-500:

Hi Christopher,

I confirm the fix! But there is a similar error happening that seems to be coming from Lucene.Net.Contrib.Highlighter.dll

I also use Lucene.Net.Contrib.Analyzers.dll but since we are configured for use of StandardAnalyzer
by default I'm not sure if there is any problem with it. I haven't seen one so far.

If I comment out the code that uses it to highlight search results, it works, but with that
code included it gives a security error.

[SecurityException: That assembly does not allow partially trusted callers.]
