Using Lucene 2.9.1, I have the following pseudocode which gets repeated at regular intervals:
1. FSDirectory dir = FSDirectory.open(java.io.File); 2. dir.setLockFactory(new SingleInstanceLockFactory()); 3. IndexWriter writer = new IndexWriter(dir, Analyzer, false, maxFieldLen) 4. writer.getReader().getVersion(); 5. writer.prepareCommit(); 6. writer.getReader().getVersion(); 7. writer.commit(); 8. writer.close(); I'm using the version number to keep external data in synch with the index. Usually, the version number from (6) is 1 greater than from (4) and the version from (4) equals the version from the previous (6). At least once a day, however, the version from (4) is 1 greater than from the previous (6). What would explain this sporadic behavior of version numbers? Thanks, Peter
