Lucene .NET 2.3.2 Security Exception - Medium trust Issues

Question

I'm only partially able to get Lucene .NET to work on GoDaddy. It throws a security exception on this line:

Hits hits = searcher.Search(query, filter);

Here are the details of this exception:

Description: The application attempted to perform an operation not allowed by the security policy.  To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

Before I give up on GoDaddy and move to DiscountASP, I wanted to check if anyone would know how I can tweak the code to operate fully in a Medium Trust environment.

Thanks.
