Lucene 9.11.1 misc API
Misc Tools
The misc package has various tools for splitting/merging indices, changing norms, finding high freq terms, and others.DirectIODirectory
DirectIODirectory is a Directory implementation that bypasses the
OS's buffer cache (using direct IO) for any IndexInput and IndexOutput
used during merging of segments larger than a specified size (default
10 MB). This avoids evicting hot pages that are still in-use for
searching, keeping search more responsive while large merges run.
See this blog post for details.
