What is Weaviate and how does it work?

Table of Contents


In today’s digital era, data is the king, and as the volume of data grows, it becomes increasingly challenging to extract useful information from it. Weaviate is an open-source vector search engine that solves this problem by providing fast and efficient searches, allowing you to find and extract data easily. This post dives into what Weaviate is, how it works, and how it can help you.

What is Weaviate?

Weaviate is an open-source, decentralized, and cloud-native vector search engine that allows you to add vector-based search functionality to your application. It uses artificial intelligence and machine learning to enable fast and efficient searches that traditional databases cannot match. It is built to handle millions/billions of vectors.

Weaviate allows you to store and search objects based on their relationships and feature vectors. An example use case can be a real estate app that uses Weaviate to group similar properties together based on factors like location, price, amenities, and more.

How does Weaviate work?

Weaviate has three main components: the REST API, the GraphQL API, and the Vector Search Engine.

The REST API is a RESTful API that allows you to manage your data and query Weaviate.

The GraphQL API is a GraphQL interface to Weaviate that allows you to efficiently query and modify your data.

The Vector Search Engine is the core of Weaviate, which uses a process called vectorization to transform each entity into a high-dimensional vector. It then stores the vector in the search engine and can use it to search for similar entities using similarity scoring algorithms.

Weaviate code with PHP client

Here’s an example of how to use the Weaviate PHP client to add and retrieve data:

require_once 'vendor/autoload.php';

use Weaviate\Client\Configuration;

$config = new Configuration();

$client = new Weaviate\Client\ApiClient($config);
$objectsApi = new Weaviate\Client\ObjectsApi($client);

// Create an object
$object = [
'class' => 'Person',
'properties' => [
'name' => 'John Smith',
'age' => 35,
'city' => 'San Francisco',

$response = $objectsApi->objectsCreate($object);
$id = $response->getId();

// Get an object
$response = $objectsApi->objectsGet($id);
$object = $response->getObject();
