# Quickstart
|
|
|
|
In this short example, you will use the Python Client to create a Collection, load data into it and run a basic search query.
|
|
|
|
<aside role="status">Before you start, please make sure Docker is installed and running on your system.</aside>
|
|
|
|
## Download and run
|
|
|
|
First, download the latest Qdrant image from Dockerhub:
|
|
|
|
```bash
|
|
docker pull qdrant/qdrant
|
|
```
|
|
|
|
Then, run the service:
|
|
|
|
```bash
|
|
docker run -p 6333:6333 \
|
|
-v $(pwd)/qdrant_storage:/qdrant/storage:z \
|
|
qdrant/qdrant
|
|
```
|
|
|
|
Under the default configuration all data will be stored in the `./qdrant_storage` directory. This will also be the only directory that both the Container and the host machine can both see.
|
|
|
|
Qdrant should now be accessible at [localhost:6333](http://localhost:6333)
|
|
|
|
## Initialize the client
|
|
|
|
```python
|
|
from qdrant_client import QdrantClient
|
|
|
|
client = QdrantClient("localhost", port=6333)
|
|
```
|
|
|
|
<aside role="status">By default, Qdrant starts with no encryption or authentication . This means anyone with network access to your machine can access your Qdrant container instance. Please read <a href="https://qdrant.tech/documentation/security/">Security</a> carefully for details on how to secure your instance.</aside>
|
|
|
|
## Create a collection
|
|
|
|
You will be storing all of your vector data in a Qdrant collection. Let's call it `test_collection`. This collection will be using a dot product distance metric to compare vectors.
|
|
|
|
```python
|
|
from qdrant_client.http.models import Distance, VectorParams
|
|
|
|
client.recreate_collection(
|
|
collection_name="test_collection",
|
|
vectors_config=VectorParams(size=4, distance=Distance.DOT),
|
|
)
|
|
```
|
|
|
|
**Response:**
|
|
|
|
```python
|
|
True
|
|
```
|
|
|
|
## Add vectors
|
|
|
|
Let's now add a few vectors with a payload. Payloads are other data you want to associate with the vector:
|
|
|
|
```python
|
|
from qdrant_client.http.models import PointStruct
|
|
|
|
operation_info = client.upsert(
|
|
collection_name="test_collection",
|
|
wait=True,
|
|
points=[
|
|
PointStruct(id=1, vector=[0.05, 0.61, 0.76, 0.74], payload={"city": "Berlin"}),
|
|
PointStruct(id=2, vector=[0.19, 0.81, 0.75, 0.11], payload={"city": "London"}),
|
|
PointStruct(id=3, vector=[0.36, 0.55, 0.47, 0.94], payload={"city": "Moscow"}),
|
|
PointStruct(id=4, vector=[0.18, 0.01, 0.85, 0.80], payload={"city": "New York"}),
|
|
PointStruct(id=5, vector=[0.24, 0.18, 0.22, 0.44], payload={"city": "Beijing"}),
|
|
PointStruct(id=6, vector=[0.35, 0.08, 0.11, 0.44], payload={"city": "Mumbai"}),
|
|
]
|
|
)
|
|
print(operation_info)
|
|
```
|
|
|
|
**Response:**
|
|
|
|
```python
|
|
operation_id=0 status=<UpdateStatus.COMPLETED: 'completed'>
|
|
```
|
|
|
|
## Run a query
|
|
Let's ask a basic question - Which of our stored vectors are most similar to the query vector `[0.2, 0.1, 0.9, 0.7]`?
|
|
|
|
```python
|
|
search_result = client.search(
|
|
collection_name="test_collection",
|
|
query_vector=[0.2, 0.1, 0.9, 0.7],
|
|
limit=3
|
|
)
|
|
print(search_result)
|
|
```
|
|
|
|
**Response:**
|
|
|
|
```python
|
|
ScoredPoint(id=4, version=0, score=1.362, payload={'city': 'New York'}, vector=None),
|
|
ScoredPoint(id=1, version=0, score=1.273, payload={'city': 'Berlin'}, vector=None),
|
|
ScoredPoint(id=3, version=0, score=1.208, payload={'city': 'Moscow'}, vector=None)
|
|
```
|
|
|
|
The results are returned in decreasing similarity order. Note that payload and vector data is missing in these results by default.
|
|
See [payload and vector in the result](../concepts/search#payload-and-vector-in-the-result) on how to enable it.
|
|
|
|
## Add a filter
|
|
|
|
We can narrow down the results further by filtering by payload. Let's find the closest results that include "London".
|
|
|
|
```python
|
|
from qdrant_client.http.models import Filter, FieldCondition, MatchValue
|
|
|
|
search_result = client.search(
|
|
collection_name="test_collection",
|
|
query_vector=[0.2, 0.1, 0.9, 0.7],
|
|
query_filter=Filter(
|
|
must=[
|
|
FieldCondition(
|
|
key="city",
|
|
match=MatchValue(value="London")
|
|
)
|
|
]
|
|
),
|
|
limit=3
|
|
)
|
|
print(search_result)
|
|
```
|
|
|
|
**Response:**
|
|
|
|
```python
|
|
ScoredPoint(id=2, version=0, score=0.871, payload={'city': 'London'}, vector=None)
|
|
```
|
|
|
|
You have just conducted vector search. You loaded vectors into a database and queried the database with a vector of your own. Qdrant found the closest results and presented you with a similarity score.
|
|
|
|
## Next steps
|
|
|
|
Now you know how Qdrant works. Getting started with [Qdrant Cloud](../cloud/quickstart-cloud/) is just as easy. [Create an account](https://qdrant.to/cloud) and use our SaaS completely free. We will take care of infrastructure maintenance and software updates.
|
|
|
|
To move onto some more complex examples of vector search, read our [Tutorials](../tutorials/) and create your own app with the help of our [Examples](../examples/).
|
|
|
|
**Note:** There is another way of running Qdrant locally. If you are a Python developer, we recommend that you try Local Mode in [Qdrant Client](https://github.com/qdrant/qdrant-client), as it only takes a few moments to get setup.
