Tutorial: Utilizing Qdrant with Cohere

In this tutorial, we will demonstrate how to use the Qdrant Vector Database to store Embeddings generated from Cohere's model and perform searches utilizing cosine similarity. We will employ the Cohere SDK to facilitate access to their powerful model. Without further ado, let’s dive into the details!

Prerequisites for Working with Qdrant

To begin this project, we will use Qdrant Cloud to host our database. Fortunately, Qdrant offers a generous 1 GB free forever memory. For assistance in setting up your Qdrant Cloud, follow the guide outlined on their website.

Setting Up Your Environment

1. Create a new virtual environment in your project directory.
2. Install required packages (e.g., Qdrant SDK, Cohere SDK).
3. Create a Python (.py) file for your project.

Data Storage in Qdrant

Our data will be stored in JSON format. You can easily replicate the structure below:

{
  "data": [
    {"id": 1, "name": "Giraffe"},
    {"id": 2, "name": "Hippopotamus"},
    {"id": 3, "name": "Rhino"}
  ]
}

Environment Variables

Create a .env file and input your Cohere API key, Qdrant API key, and the Qdrant host to streamline access.

Importing Libraries

Load the necessary environment variables by importing libraries such as os and dotenv.

Indexing Data and Searching

We will develop the SearchClient class responsible for indexing and accessing our data efficiently. This class will encapsulate all the required functionalities—indexing, searching, and data conversion as needed.

Implementing the SearchClient

Your next step is to implement the functionality for reading from the data.json file, processing the data, indexing, and subsequently searching for top results from our Database.

Sample Code

Below is a simplified illustration of how this can be structured:

class SearchClient:
    def __init__(self):
        # Initialize connection to Qdrant and other setups
        pass

    def index_data(self, data):
        # Code for indexing data
        pass

    def search(self, query):
        # Code for performing search
        pass

Evaluating Results

Once you’ve indexed the data, try to retrieve the top three search results. For instance, the first row may indicate a successful index operation, returning results that include a Giraffe, Hippopotamus, and Rhino—showing the power of vector similarity in revealing contextual relevance.

The Next Steps: Harnessing Qdrant and Cohere for Your AI Applications

Equipped with the foundational knowledge of Qdrant, what lies ahead in your AI expedition?

• Consider creating an API that indexes data, allows adding new records, and performs searches. FastAPI is an excellent framework to utilize.
• Participate in AI Hackathons to refine your skills and collaborate with a global community of innovators eager to leverage AI.
• Engage with ongoing events and opportunities designed to expand your boundaries in AI.

As you embark on this exciting journey, don't forget to continuously challenge yourself and explore innovative solutions that harness the potential of vector similarity in your applications.
