Before going forward, make sure you have the app running either locally or in a cloud provider of your choice. If hosting it somewhere, replace`localhost:8000` with the URL and port of your service.

The simplest way to interact with it is to use cURL oranHTTP client of your preference. If running in debug mode locally, the Rest Framework provides a nice web UI which you can access on[http://localhost:8000/api/todos/](http://localhost:8000/api/todo/) using a browser.

To create a to-do item with cURL, you can just run this:

The embedding contains 384 floating point numbers; we removed most of them in this blog post to make sure it fits on the page.

You can try creating multiple to-do items for fun and profit. If the description is changed, so will the embedding, demonstrating how the`intfloat/e5-small` modelis understanding the semantic meaning of your text.

Once you have a few embeddings and to-dos stored in your database, the fun part of searching can begin. In a typical search example with PostgreSQL, you'd now be using`tsvector` to keyword match your to-dos to the search query with term frequency. That's a good technique, but semantic search is better.

We've created a simplesearch endpointthataccepts a query, a completed to-do filter, and a limit. To use it, you can justdo this:

If you've created a bunch of different to-do items, you should get only one search result back, and exactly the one you were expecting:

You can increase the`limit` to something larger and you should get more documents, in decreasing order of relevance.
