And here is a sample code: read docs from original index and then write to an new one.
void CreateNewIndex(string OrgIndex)
{
IndexReader reader = IndexReader.Open(OrgIndex);
IndexWriter writer = new IndexWriter("Floyd", new Lucene.Net.Analysis.WhitespaceAnalyzer(),true);
for (int i = 0; i < reader.MaxDoc(); i++)
{
if (reader.IsDeleted(i) == true) continue;
Lucene.Net.Documents.Document orgDoc = reader.Document(i);
System.Collections.IList fields = orgDoc.GetFields();
Lucene.Net.Documents.Document newDoc = new Document();
foreach (Lucene.Net.Documents.Field field in fields)
{
Lucene.Net.Documents.Field newField = new Field(
System.Convert.ToBase64String( System.Text.Encoding.UTF8.GetBytes(field.Name())), //ç
//field.Name(), //ç
field.StringValue(),
field.IsStored() ? Lucene.Net.Documents.Field.Store.YES : Lucene.Net.Documents.Field.Store.NO,
field.IsTokenized() ? Lucene.Net.Documents.Field.Index.TOKENIZED : Lucene.Net.Documents.Field.Index.UN_TOKENIZED);
newDoc.Add(newField);
}
writer.AddDocument(newDoc);
}
writer.Close();
reader.Close();
}
If some field names are chinese, then Luke returns “read past EOF”. But if those field names are replaced with non-chinese names, then it works.

Subject: Luke-0.9.x cannot open index files
Digy,
Some additional information from the discussion on the lucene-net-user list with Floyd Wu.
I ran some further tests using Java Lucene 2.3.2 and JDK 1.5.
The Java equivalents of the two small test applications I use to inspect an index and compact it, function identically to the .NET versions (that were built with VS2005 and Lucene.NET 2.3.1).
That Luke cannot open the index appears to be a problem within Luke.
Even if Floyd's index contains some odd entries, Java Lucene 2.3.2 does not flag the index as corrupt; and both the Java and .NET versions report the same index content before and after the optimize operation.

Digy commented on LUCENENET-169:
--------------------------------
Although you can overcome all of them somehow;
* controlling the the lifetime of IndexWriter/IndexReader in a naturally manner,
* reopening the IndexReader only when needed using (for ex) FileSystemWatcher,
* providing a separation between data & bussiness layer,
* providing other apps an interface that may want to write its own user interface,
* accessing a single search service from different web apps/from load balanced web servers
* controlling the lifetime of searching/indexing code (without being effected by the restart of the IIS processes automatically when some memory limit is exceeded (for ex.) )
* Ability to access some system resources that can be restricted by IIS
etc.
make me think a separete search service is a better idea.But at last, it is a design decision of you.
(Think, A WebApp+Solr in Java world)

Re: Luke-0.9.x cannot open index files
Posted by Floyd Wu <fl...@gmail.com>.
Hi Digy,
Will this bug affects the normal use of Lucene.Net?
Or this bug will only existed in Luke? It seems that my system work fine
with index contained chinese as field name.
Are there any potential problem if continue using chinese as field name?
Thanks
Floyd

Subject: RE: Luke-0.9.x cannot open index files
Floyd,
Here is a simple Java command-line application that displays the content of an index. It successfully opens your "documents" index using Java Lucene version 2.3.2 (the closest version to current Lucene.NET).
That this program works properly with your index, but Luke does not, shows that the problem is within Luke. You can provide this program with your index and bug report to the people supporting Luke.

Thanks DIGY
So will you report this to Luke author or Java Lucene group?
I've been reported this situation to Luke author and he( or she) doesn't
think this is a bug of Luke.

Floyd,
Here is a simple Java command-line application that displays the content of an index. It successfully opens your "documents" index using Java Lucene version 2.3.2 (the closest version to current Lucene.NET).
That this program works properly with your index, but Luke does not, shows that the problem is within Luke. You can provide this program with your index and bug report to the people supporting Luke.

Thanks DIGY
So will you report this to Luke author or Java Lucene group?
I've been reported this situation to Luke author and he( or she) doesn't

RE: Luke-0.9.x cannot open index files
Posted by "Granroth, Neal V." <ne...@thermofisher.com>.
Floyd,
Here is a simple Java command-line application that displays the content of an index. It successfully opens your "documents" index using Java Lucene version 2.3.2 (the closest version to current Lucene.NET).
That this program works properly with your index, but Luke does not, shows that the problem is within Luke. You can provide this program with your index and bug report to the people supporting Luke.

Subject: Re: Luke-0.9.x cannot open index files
Thanks DIGY
So will you report this to Luke author or Java Lucene group?
I've been reported this situation to Luke author and he( or she) doesn't
think this is a bug of Luke.

Re: Luke-0.9.x cannot open index files
Posted by digy digy <di...@gmail.com>.
It is not a bug of Lucene.Net and as my sample code shows, Lucene.Net works
well with chinese field names.
I think, it is a bug in Luke.

Re: Luke-0.9.x cannot open index files
Posted by Floyd Wu <fl...@gmail.com>.
Hi Digy,
Thanks for your help.
But if chinese field name is the problem, will it be "fix" in Lucene.Net or
how can I avoid this problem.
Chinese field name is by design and probably not avoidable.

>
> Although you can overcome all of them somehow;
>
>
>
> * controlling the the lifetime of IndexWriter/IndexReader in a naturally
> manner,
>
> * reopening the IndexReader only when needed using (for ex)
> FileSystemWatcher,
>
> * providing a separation between data & bussiness layer,
>
> * providing other apps an interface that may want to write its own user
> interface,
>
> * accessing a single search service from different web apps/from load
> balanced web servers
>
> * controlling the lifetime of searching/indexing code (without being
> effected by the restart of the IIS processes automatically when some memory
> limit is exceeded (for ex.) )
>
> * Ability to access some system resources that can be restricted by IIS
>
> etc.
>
> make me think a separete search service is a better idea.But at last, it is
> a design decision of you.
