So that could be built on Windows and used with Mono?

Current version of Lucene.Net in svn-trunk (2.3.1) is stable and can be compiled without any error. Use project/solution file to compile the project. I personally use Visual C# 2005 Express Edition. You will get thousands of warnings about unused variables or XML documentation but it is OK. 

Yeah, but it looks like he is using mono c# compiler, which basically
tries to build all .cs files in the directory (I think). Maybe there
are some left over, undeleted files hanging around in directories that
are not part of VS IDE project file.

Subject: Building Lucene.Net from SVN

I've checked out the latest revision lately, then tried to build
Lucene by using the following command:

$ gmcs -t:library -r:System.Configuration `find Lucene.Net -name
'*.cs' ! -name RemoteSearchable.cs -type f` -out:Lucene.Net.dll

Here is what I got:

Lucene.Net/Analysis/Standard/TokenMgrError.cs(49,18): error CS8025:

Lucene.Net/Index/DocumentWriter.cs(126,57): error CS8025: Parsing error

`SegmentReader'
Lucene.Net/Index/SegmentReader.cs(34,22): (Location of the symbol
related to previous error)
Compilation failed: 3 error(s), 0 warnings

I removed SegmentReade-2r.cs, fixed the messed up comments in
TokenMgrError.cs and DocumentWriter.cs and tried again.  Here's the
result:

I don't wanna hack Lucene just to build it and I cannot use the latest 
build because it is 14 months old and works horribly slowly.  I'm
extremely disappointed about the current state of Lucene.Net.

Anybody has any suggestion how to build Lucene.Net from the SVN?

What version of Lucene.net are you using? I found that when I built the latest version from source the index building was blazingly fast compared to the latest binaries on the website.

Subject: IndexWriter.AddDocument is slow

Hi List,

It takes pretty long time to index documents using Lucene.Net.  It
takes about 3 seconds to add thounsand documents to the index.  I've
used Java Lucene in the past and according to my memories indexing
should be about 20 times faster.

Here's the relevant code:

          IndexWriter index_writer = new IndexWriter("index", new
StandardAnalyzer(), true);
//            index_writer.SetMergeFactor(10000);
//            index_writer.SetMaxMergeDocs(10000);
//            index_writer.SetMaxBufferedDocs(10000);
          ExecuteSqlQuery("SELECT artist, title FROM songname");
          int count = 0;
          while (reader.Read()) {
              if (count > 0 && count%1000 == 0) {
                  Console.WriteLine(count);
              }
              Document document = new Document();
              document.Add(new Field("artist",
reader.GetString("artist"), Field.Store.YES, Field.Index.TOKENIZED)); 
              document.Add(new Field("title",
reader.GetString("title"), Field.Store.YES, Field.Index.TOKENIZED));
              index_writer.AddDocument(document);
              count++;
          }

When decommenting the commented lines indexing gets about 2x faster,
but it's not really significant.

I'd really appreciate your insights about this speed issue.

Thanks in advance!
