Migration to Lucene 4.1

[Paul Sitowitz <si...@gmail.com>]

Hello,

I currently have the following production code which currently works with
Lucene 3.0:

this.luceneWriter = new IndexWriter( directory, analyzer, true,
MaxFieldLength.UNLIMITED );
this.fs.delete( this.finalOutput, true );
this.luceneWriter.setUseCompoundFile( true );
this.luceneWriter.setMergeFactor( job.getInt( "indexer.mergeFactor", 1000 )
);
this.luceneWriter.setMaxBufferedDocs( job.getInt( "indexer.minMergeDocs",
1000 ) );
this.luceneWriter.setMaxMergeDocs( job.getInt( "indexer.maxMergeDocs",
Integer.MAX_VALUE ) );

LuceneMergeRecordWriter.this.setStatus( "Adding indexes" );
LuceneMergeRecordWriter.this.luceneWriter.addIndexesNoOptimize(
LuceneMergeRecordWriter.this.luceneIndexes
                                        .toArray( new
Directory[LuceneMergeRecordWriter.this.luceneIndexes.size()] ) );

LuceneMergeRecordWriter.this.setStatus( "Optimizing index" );
LuceneMergeRecordWriter.this.luceneWriter.optimize()

I am in the process of upgrading to Lucene 4.1 but have run into some
unknown API issues. Can someone help to point out what the equivalent 4.1
code would look like?

Here is some of the partial 4.1 code that I have thus far:

        this.fs.delete( this.finalOutput, true );
        IndexWriterConfig iwconf = new IndexWriterConfig(Version.LUCENE_41,
analyzer);
        iwconf.setOpenMode( IndexWriterConfig.OpenMode.CREATE );
        iwconf.setMaxBufferedDocs( conf.getInt( "indexer.minMergeDocs",
1000 ) );
        ..................
        this.luceneWriter = new IndexWriter( directory, iwconf );

Thanks,

Paul

Have you read the changes and migration docs that come with 4.1?  You
may also need to look at 3.[123456] javadocs to see deprecations and
alternatives for stuff that was present in 3.0 but gone in 4.1.
