Overview

The following article was helpful for integrating Strapi with Elasticsearch.

How to integrate Elasticsearch with Strapi

This post details the implementation specifics to setup Elasticsearch with Strapi. This includes triggering Elasticsearch indexing via Strapi customization and providing a Strapi route endpoint to front the Elasticsearch search. These integrations are detailed through an example blog-post Strapi collection.

The source code is also publicly available.

Here, I will note some customizations made based on the above article, including integration with Amazon OpenSearch.

The customized source code is available here:

Modifications

The article references indexing_type, but it needed to be changed to indexing_request_type.

Additionally, to use Amazon OpenSearch instead of Elasticsearch, the following libraries need to be installed.

npm install @opensearch-project/opensearch
npm install @aws-sdk/credential-providers

There are several authentication methods available, but here I made the following changes.

The index registration and deletion processes also needed to be modified as follows.

As a result of these modifications, I was able to connect Strapi with Amazon OpenSearch.

By modifying elastic/elasticClient.js and src/api/search/controllers/search.js, I was also able to customize the API output. This enabled the use of Elasticsearch Aggregations. (Due to my limited investigation, this may also be achievable with Strapi alone.)
