📦 Installation

pip install vittoriadb

The package automatically downloads the appropriate VittoriaDB binary for your platform during installation.

🚀 Quick Start

Basic Usage

import vittoriadb

# Auto-starts VittoriaDB server and connects
db = vittoriadb.connect()

# Create a collection
collection = db.create_collection(
    name="documents",
    dimensions=384,
    metric="cosine"
)

# Insert vectors with metadata
collection.insert(
    id="doc1",
    vector=[0.1, 0.2, 0.3] * 128,  # 384 dimensions
    metadata={"title": "My Document", "category": "tech"}
)

# Search for similar vectors
results = collection.search(
    vector=[0.1, 0.2, 0.3] * 128,
    limit=5,
    include_metadata=True
)

for result in results:
    print(f"ID: {result.id}, Score: {result.score:.4f}")
    print(f"Metadata: {result.metadata}")

# Close connection
db.close()

Automatic Text Embeddings (🚀 NEW!)

import vittoriadb
from vittoriadb.configure import Configure

# Connect to VittoriaDB
db = vittoriadb.connect()

# Create collection with automatic embeddings
collection = db.create_collection(
    name="smart_docs",
    dimensions=384,
    vectorizer_config=Configure.Vectors.auto_embeddings()  # 🎯 Server-side embeddings!
)

# Insert text directly - embeddings generated automatically!
collection.insert_text(
    id="article1",
    text="Artificial intelligence is transforming how we process data.",
    metadata={"category": "AI", "source": "blog"}
)

# Batch insert multiple texts
texts = [
    {
        "id": "article2",
        "text": "Machine learning enables computers to learn from data.",
        "metadata": {"category": "ML"}
    },
    {
        "id": "article3", 
        "text": "Vector databases provide efficient similarity search.",
        "metadata": {"category": "database"}
    }
]
collection.insert_text_batch(texts)

# Search with natural language queries
results = collection.search_text(
    query="artificial intelligence and machine learning",
    limit=3
)

for result in results:
    print(f"Score: {result.score:.4f}")
    print(f"Text: {result.metadata['text'][:100]}...")

db.close()

Document Upload and Processing

import vittoriadb
from vittoriadb.configure import Configure

db = vittoriadb.connect()

# Create collection with vectorizer for automatic processing
collection = db.create_collection(
    name="knowledge_base",
    dimensions=384,
    vectorizer_config=Configure.Vectors.auto_embeddings()
)

# Upload and process documents automatically
result = collection.upload_file(
    file_path="research_paper.pdf",
    chunk_size=600,
    chunk_overlap=100,
    metadata={"source": "research", "year": "2024"}
)

print(f"Processed {result['chunks_created']} chunks")
print(f"Inserted {result['chunks_inserted']} vectors")

# Search the uploaded content
results = collection.search_text(
    query="machine learning algorithms",
    limit=5
)

db.close()

🎛️ Vectorizer Configuration

config = Configure.Vectors.openai_embeddings(
    api_key="your-openai-api-key",
    model="text-embedding-ada-002",
    dimensions=1536
)

HuggingFace Models

config = Configure.Vectors.huggingface_embeddings(
    api_key="your-hf-token",  # Optional for public models
    model="sentence-transformers/all-MiniLM-L6-v2",
    dimensions=384
