- Added support for per-document values (DocValues). DocValues can be used for custom
scoring factors (accessible via Similarity), for pre-sorted Sort values, and more.
- When indexing via multiple threads, each IndexWriter thread now flushes its own segment
to disk concurrently, resulting in substantial performance improvements
