A history of neural search and its evolution through the years


Table of contents :


The concept of searching for information through machines has been around for decades. However, in the early days, the algorithm for search was focused on keyword matching, where the search engine would look for exact matches between the word typed in the search bar and the content on the page.

As the internet evolved, so did the technology behind searching. One such advancement is the introduction of neural search, which has revolutionized the way we look for information online. In this post, we will explore the history of neural search, its evolution through the years, and how it has impacted the search experience.

The Advent of Neural Search

Neural search is based on neural networks, which are a type of machine learning model that can recognize patterns and make predictions. Unlike traditional search algorithms, neural search is focused on understanding the intent behind a query and returning results based on that understanding.

The first neural search engine can be traced back to 2012 when Google introduced its Knowledge Graph. This technology was capable of understanding the relationships between different concepts, thereby improving the search experience for users. As a result, users could find more relevant information without having to sift through irrelevant content.

The use of neural networks as a search algorithm gained further traction in 2014 when Facebook introduced its DeepFace. This technology was capable of recognizing faces in photos with incredible accuracy. While not specifically a search engine, this technology set the path for the use of neural networks for searching.

The year 2015 saw a significant breakthrough in the evolution of neural search when Google introduced RankBrain. This technology was capable of processing and understanding natural language queries, thus making search more intelligent. RankBrain was the first step towards making search smarter and more intuitive than it had ever been before.

The Evolution of Neural Search

After the introduction of RankBrain, neural search evolved with incredible speed. Google introduced BERT in 2019, which takes this evolution to the next level. BERT leverages transformer neural networks, enabling search algorithms to understand the context of a query and provide more relevant results.

BERT has set the path for future advancements in neural search, including the possibility of combining language and visual search. The combination of these two search modes would allow users to search for images by describing what they see, making search even more intuitive and efficient.

WPSOLR and Neural Search

WPSOLR is a WordPress plugin that integrates Elasticsearch, a powerful search engine capable of handling immense amounts of data. With WPSOLR, users can create custom search experiences for their websites, taking advantage of the technology behind neural search.

The WPSOLR plugin allows users to configure search settings to match their specific needs. This configuration includes the ability to use Elasticsearch’s fuzzy search, which improves the accuracy of search results by returning results that match the intent behind the query, even if the words used in the query are not an exact match.

WPSOLR also provides users with the ability to filter search results, ensuring that users find exactly what they’re looking for. With its intuitive interface and easy-to-use features, WPSOLR is an excellent tool for those looking to take advantage of the latest advancements in neural search algorithms.


Neural search has come a long way since its inception. From the introduction of Google’s Knowledge Graph to the more recent advancements in transformer neural networks, it’s clear that this technology will continue to evolve and revolutionize the way we search for information online.

Plugins like WPSOLR make it easier for developers and website owners to take advantage of the latest advancements in neural search algorithms, delivering a better search experience for website visitors. So, if you’re looking to improve your website’s search capabilities, consider integrating WPSOLR into your website today.

// Sample PHP code using Elasticsearch with WPSOLR plugin

use Elasticsearch\ClientBuilder;

$client = ClientBuilder::create()->build();

$params = [
    'index' => 'my_index',
    'body'  => [
        'query' => [
            'match' => [
                'my_field' => 'my_query',

$response = $client->search($params);
