Thanks!
I have learned Solr as a power user and written a couple of simple
filters. I'm not a Lucene heavy. Where is this in Lucene? Is it the
default? I don't remember Lucene having the notion of a unique id
(primary key).
In this merge code, with the latest Lucene 2.3, will the duplicates in
solr/data1 override the records in solr/data0? Or the other way around?
How do I add the new Lucene implementation?
try {
IndexWriter writer = new IndexWriter(new
File("solr/data0/index"),
new StandardAnalyzer(), false);
Directory[] dirs = new
Directory[]{FSDirectory.getDirectory(new File("solr/data1/index"))};
System.out.println(writer);
writer.addIndexes(dirs);
writer.close();
} catch (Exception e) {
e.printStackTrace();
}
Thanks,
Lance Norskog

Yes.

Both. It was originally just in Solr, but Lucene now has an
implementation.
Neither implementation will prevent this as both just remember documents
(in memory) that were added and then periodically delete older documents
with the same id.
