Hi Floyd,
For ex, see the sample code below: If you lock IndexWriter the indexing code
gets stuck. But If you don't use the lock and let the Lucene do it
internally, indexing goes fine. Maybe your index gets corrupted with such a
code?

Subject: Re: Luke-0.9.2 cannot open index files
Hi Digy,
here is my code for add a document to lucene
internal static void AddContent(Content content)
{
lock (writer)
{
writer.Open();
try
{
writer.AddContent(content);
}
finally
{
writer.Close();
}
}
}
No magic, just like ordinary usage.
