Hi,
Will this work for solr indexes?? Since they are compatible it has to work, but in my case it is giving corrupt index exception..

I’ve been looking around blog.asteriosk.gr and actually am impressed by the exceptional content material here. I work the nightshift at my job and it is boring. I’ve been coming right here for the past couple nights and reading. I simply needed to let you know that I have been enjoying what I’ve seen and I look ahead to reading more.

Hi there, many thanks. This helped very well! IndexModifier is deprecated and lacked performance, so this is a very good alternative to work with…

Cool, thanks a lot Javier! I will try to run it myself and post the updated code!

Sorry the number of lines were missing…

LINE 55
IndexWriter writer = new IndexWriter( INDEX_DIR,
new StandardAnalyzer(),
true,
IndexWriter.MaxFieldLength.UNLIMITED);

LINE 65
indexes[i] = FSDirectory.open(new File(INDEXES_DIR.getAbsolutePath()+ “/” + INDEXES_DIR.list()[i]));

LINE 70
writer.addIndexesNoOptimize(indexes);

Yes, a few things have changed in lucene 3.0. You will have to replace the following lines:

IndexWriter writer = new IndexWriter( INDEX_DIR,
new StandardAnalyzer(),
true,
IndexWriter.MaxFieldLength.UNLIMITED);

indexes[i] = FSDirectory.open(new File(INDEXES_DIR.getAbsolutePath()+ “/” + INDEXES_DIR.list()[i]));

writer.addIndexesNoOptimize(indexes);

I think that is all, it works perfect, thanks for sharing your code!!

Hi, I think I used Lucene 2.9.1 and I suppose that its not compatible with Lucene 3.0. Try to see which part of the code is causing the problem and if you find it, please let me know!
