Research direction

The issue names no Lucene files, tests, or entry points. Start by locating the current skip-list indexing path, then review the referenced Princeton BTree.java example and Lucene's indexing architecture. Done would require an agreed B-tree design, implementation scope, and tests showing it supports the stated large-volume search use case.
