# Chapter 03 – Knowledge‑Base (VectorDB) Documentation Overview

This chapter explains how GeneralBots manages knowledge‑base collections, indexing, caching, and semantic search. The implementation uses vector databases for semantic search and highlights the use of the **.gbdrive** package for storage when needed.

| Document | File | Description |
|----------|------|-------------|
| **README** | [README.md](README.md) | High‑level reference for the `.gbkb` package and its core commands (`USE KB`, `CLEAR KB`, `USE WEBSITE`). |
| **Caching** | [caching.md](caching.md) | Optional in‑memory and persistent SQLite caching to speed up frequent `FIND` queries. |
| **Context Compaction** | [context-compaction.md](context-compaction.md) | Techniques to keep the LLM context window within limits (summarization, memory pruning, sliding window). |
| **Indexing** | [indexing.md](indexing.md) | Process of extracting, chunking, embedding, and storing document vectors in the VectorDB. |
| **Semantic Caching** | [caching.md](caching.md) | Intelligent caching for LLM responses, including semantic similarity matching. |
| **Semantic Search** | [semantic-search.md](semantic-search.md) | How the `FIND` keyword performs meaning‑based retrieval using the VectorDB. |
| **Vector Collections** | [vector-collections.md](vector-collections.md) | Definition and management of vector collections, including creation, document addition, and usage in dialogs. |
