🚀 Auto Embeddings: AI Search Made Easy

The highlight of Manticore Search 13.11.0 is Auto Embeddings — a game-changing feature that makes semantic search as easy as SQL. No need for external services or complex pipelines: just insert text and search with natural language.

What Auto Embeddings Offer:

✨ Automatic embedding generation from your text

✨ Natural language queries that understand meaning, not just keywords

✨ Support for multiple models (OpenAI, Hugging Face, Voyage, Jina)

✨ Smooth integration with SQL and JSON APIs

Quick Example

-- Create table with auto-embeddings
CREATE TABLE products (
    title TEXT,
    description TEXT,
    vector FLOAT_VECTOR KNN_TYPE='hnsw' HNSW_SIMILARITY='l2'
        MODEL_NAME='sentence-transformers/all-MiniLM-L6-v2'
        FROM='title,description'
);

-- Insert data (embeddings generated automatically)
INSERT INTO products(id, title, description) VALUES
  (1, 'wireless headphones', 'Bluetooth headphones with noise cancellation'),
  (2, 'hiking backpack', 'Lightweight backpack for outdoor adventures');

-- Search with natural language
SELECT id, title
FROM products 
WHERE knn(vector, 3, 'portable audio device for music');

Results:

+------+---------------------+
| id   | title               |
+------+---------------------+
|    1 | wireless headphones |
...
+------+---------------------+

Here, semantic search correctly matched "wireless headphones" with the phrase "portable audio device for music," even though no keywords overlapped.
