Use fastembed library to easily encode & index documents into qdrant


pip install fastembed qdrant-client


python
from qdrant_client import QdrantClient

Initialize the client
client = QdrantClient(":memory:") or QdrantClient(path="path/to/db")

Prepare your documents, metadata, and IDs
docs = ["Qdrant has Langchain integrations", "Qdrant also has Llama Index integrations"]
metadata = [
{"source": "Langchain-docs"},
{"source": "Linkedin-docs"},
]
ids = [42, 2]

Use the new add method
client.add(
collection_name="demo_collection",
documents=docs,
metadata=metadata,
ids=ids
)

search_result = client.query(
collection_name="demo_collection",
query_text="This is a query document"
)
print(search_result)

Local Mode

Introduce a new way to run Qdrant from python, no server required!



Python client allows you to run same code in local mode without running Qdrant server.

Simply initialize client like this:

python
from qdrant_client import QdrantClient

client = QdrantClient(":memory:")
or
client = QdrantClient(path="path/to/db") Persists changes to disk


Local mode is useful for development, prototyping and testing.

- You can use it to run tests in your CI/CD pipeline.
- Run it in Colab or Jupyter Notebook, no extra dependencies required. See an [example](https://colab.research.google.com/drive/1Bz8RSVHwnNDaNtDwotfPj0w7AYzsdXZ-?usp=sharing)
- When you need to scale, simply switch to server mode.

How it works?

We just implemented Qdrant API in pure Python.
We covered it with tests extensively to be sure it works the same as the server version.
