Definition
A hierarchical data structure that organizes document chunks or embeddings into nested nodes, where parent nodes often represent semantic summaries of their children. This architecture enables multi-granular retrieval, allowing an agent to traverse from broad thematic summaries down to specific factual segments, balancing high-level context with granular precision.
Unlike flat vector indices that prioritize nearest-neighbor search speed, tree-based indices focus on recursive summarization and hierarchical context navigation.
