# haiku.rag
|
||
|
||
`haiku.rag` is a Retrieval-Augmented Generation (RAG) library built to work with LanceDB as a local vector database. It uses LanceDB for storing embeddings and performs semantic (vector) search as well as full-text search combined through native hybrid search with Reciprocal Rank Fusion. Both open-source (Ollama, MixedBread AI) as well as commercial (OpenAI, VoyageAI) embedding providers are supported.
|
||
|
||
> **Note**: Starting with version 0.7.0, haiku.rag uses LanceDB instead of SQLite. If you have an existing SQLite database, use `haiku-rag migrate old_database.sqlite` to migrate your data safely.
|
||
|
||
## Features
|
||
|
||
- **Local LanceDB**: No need to run additional servers
|
||
- **Support for various embedding providers**: Ollama, VoyageAI, OpenAI or add your own
|
||
- **Native Hybrid Search**: Vector search combined with full-text search using native LanceDB RRF reranking
|
||
- **Reranking**: Optional result reranking with MixedBread AI or Cohere
|
||
- **Question Answering**: Built-in QA agents using Ollama, OpenAI, or Anthropic.
|
||
- **File monitoring**: Automatically index files when run as a server
|
||
- **Extended file format support**: Parse 40+ file formats including PDF, DOCX, HTML, Markdown, code files and more. Or add a URL!
|
||
- **MCP server**: Exposes functionality as MCP tools
|
||
- **CLI commands**: Access all functionality from your terminal
|
||
- Add sources from text, files, or URLs, optionally with a human‑readable title
|
||
- **Python client**: Call `haiku.rag` from your own python applications
|
||

## Quick Start
|
||
|
||
Install haiku.rag:
|
||
```bash
|
||
uv pip install haiku.rag
|
||
```
|
||
|
||
Use from Python:
|
||
```python
|
||
from haiku.rag.client import HaikuRAG
|
||
|
||
async with HaikuRAG("database.lancedb") as client:
|
||
# Add a document
|
||
doc = await client.create_document("Your content here")
|
||
|
||
# Search documents
|
||
results = await client.search("query")
|
||
|
||
# Ask questions
|
||
answer = await client.ask("Who is the author of haiku.rag?")
|
||
```
|
||
|
||
Or use the CLI:
|
||
```bash
|
||
haiku-rag add "Your document content"
|
||
haiku-rag add-src /path/to/document.pdf --title "Q3 Financial Report"
|
||
haiku-rag search "query"
|
||
haiku-rag ask "Who is the author of haiku.rag?"
|
||
haiku-rag migrate old_database.sqlite # Migrate from SQLite
