Examples of KeepOnlyLastCommitDeletionPolicy

org.apache.lucene.index.KeepOnlyLastCommitDeletionPolicy
This {@link IndexDeletionPolicy} implementation thatkeeps only the most recent commit and immediately removes all prior commits after a new commit is done. This is the default deletion policy.

Examples of org.apache.lucene.index.KeepOnlyLastCommitDeletionPolicy

      Directory dir =
          new FileSystemDirectory(fs, new Path(shards[i].getDirectory()),
              false, conf);
      IndexWriter writer =
          new IndexWriter(dir, false, null,
              new KeepOnlyLastCommitDeletionPolicy());
      writer.close();
    }


    // verify the number of segments, must be done after an writer with
    // KeepOnlyLastCommitDeletionPolicy so that earlier checkpoints are removed
