Hi
I am running into problems using Lucence 2.9.2 in a medium trust
environment, namely Rackspace cloud. I have added the following line to
assembleyinfo.cs
[assembly: AllowPartiallyTrustedCallers()]
However the following code produces the error below
FSDirectory directory = FSDirectory.Open(new
DirectoryInfo(Server.MapPath("~/App_Data/LuceneIndex")));
Analyzer analyzer = new
StandardAnalyzer(Version.LUCENE_29);
var writer = new IndexWriter(directory, analyzer, true,
IndexWriter.MaxFieldLength.LIMITED);
writer.AddDocument(...);
writer.Optimize();
writer.Close();
The directory "LuceneIndex" is being created, does anyone have a fix for
this?
