jina 2.0.0rc2.dev38

Jina is the cloud-native neural search solution powered by the state-of-the-art AI and deep learning

Cloud-Native Neural Search Framework for Any Kind of Data

Powered by deep learning and cloud-native techniques, Jina is geared towards building search systems for any kind of data in just minutes.

🌌 Search anything - Large-scale indexing and querying of unstructured data: video, image, long/short text, music, source code, PDF, etc.

⏱️ Save time - The design pattern of neural search systems, from zero to a production-ready system in minutes.

🍱 Own your stack - Keep an end-to-end stack ownership of your solution, avoid the integration pitfalls with fragmented, multi-vendor, generic legacy tools.

🌩️ Fast & cloud-ready - Decentralized architecture from day one. Scalable & cloud-native by design: enjoy containerizing, distributing, sharding, async, REST/gRPC/WebSocket.

Get Started

Document, Executor, Flow are three fundamental concepts in Jina.

• 📄 Document is the basic data type in Jina;
• ⚙️ Executor is how Jina processes Documents;
• 🔀 Flow is how Jina streamlines and distributes Executors.

Copy-paste the minimum example below and run it:

from jina import Document, Executor, Flow, requests


class MyExecutor(Executor):

    @requests(on='/bar')
    def foo(self, docs, parameters, **kwargs):
        for d in docs:
            d.text = parameters['p1']


f = Flow().add(uses=MyExecutor)
d = Document(text='hello')

with f:
    f.post('/bar', d, parameters={'p1': 'world'}, on_done=print)

Run Quick Demo

• 👗 Fashion image search: jina hello fashion
• 🤖 QA chatbot: pip install "jina[chatbot]" && jina hello chatbot
• 📰 Multimodal search: pip install "jina[multimodal]" && jina hello multimodal

Fork Demo & Build Your Own

Copy the source code of a hello world to your own directory and start from there:

$ jina hello fork fashion ../my-proj/
