Key: LUCENE-521
URL: http://issues.apache.org/jira/browse/LUCENE-521
Project: Lucene - Java
Type: Bug
Components: Index
Versions: 1.9
Environment: Windows XP, J2EE 1.4
Reporter: Keith Morgan
Disk index does not get updated unless 10 or more documents exist in a RAM
directory.
Below is the code used:
//Adding documents to RAMDirectory
RAMDirectory ramDirectory = new RAMDirectory();
IndexWriter ramWriter = new IndexWriter(ramDirectory, new StandardAnalyzer(),
true);
......code looping and adding docs to IndexWriter
ramWriter.addDocument(doc);
WriteIndex.writeRAMDirectory(ramDirectory);
//Sending RAMDirectory to Disk
public static void writeRAMDirectory(RAMDirectory ramDirectory) {
boolean exists = IndexReader.indexExists(indexDir);
IndexWriter diskWriter = new IndexWriter(indexDir, new StandardAnalyzer(),
!exists);
diskWriter.setMergeFactor(1000);
diskWriter.setMaxMergeDocs(10000);
diskWriter.addIndexes(new Directory[] { ramDirectory });
}
