# Create configuration
config = KnowledgeConfig(
    embedding_provider="openai",
    embedding_model="text-embedding-3-small",
    embedding_dimension=1536,
)

# Initialize service
service = KnowledgeService(config)

# Add knowledge from text
await service.add_knowledge(
    content="The capital of France is Paris.",
    content_type="text/plain",
    filename="facts.txt",
)

# Search for knowledge
results = await service.search("What is the capital of France?")
for result in results:
    print(f"Score: {result.similarity:.2f} - {result.content}")
