Using Elasticsearch with Magento

Elasticsearch is a powerful search engine that improves product search speed and accuracy in Magento. It replaces the default MySQL search with a scalable, full‑text search solution. On ruachost.com, Elasticsearch is supported for Magento 2.4 and later.

Why Use Elasticsearch?

Provides fast, relevant search results for customers.
Supports advanced features like autocomplete, synonyms, and spell correction.
Scales easily for large catalogs with thousands of products.
Improves overall site performance compared to MySQL search.

Steps to Configure Magento with Elasticsearch

Step 1: Ensure Elasticsearch is Installed

On Managed VPS/Dedicated Servers → Ruachost support can install Elasticsearch for you.
On Unmanaged VPS → Install manually via SSH:
Terminal window
```
apt-get install elasticsearch
```
or
Terminal window
```
yum install elasticsearch
```

Step 2: Configure Magento to Use Elasticsearch

Log in to Magento Admin.
Go to Stores → Configuration → Catalog → Catalog Search.
Under Search Engine, select Elasticsearch.
Configure the following settings:
- Elasticsearch Server Hostname → 127.0.0.1 (or your server’s IP).
- Elasticsearch Server Port → 9200.
- Index Prefix → Optional, useful for multiple Magento installations.
- Enable Elasticsearch HTTP Auth → Yes/No depending on your setup.
- Elasticsearch Server Timeout → Recommended: 15.
Save configuration.

Step 3: Test Elasticsearch Integration

Run reindexing via CLI:
Terminal window
```
php bin/magento indexer:reindex
```
Clear cache:
Terminal window
```
php bin/magento cache:flush
```
Test product search in your storefront.

Important Notes

Elasticsearch is required for Magento 2.4 and newer.
Ensure your server meets memory requirements (at least 2GB RAM for Elasticsearch).
If using multiple stores, configure separate index prefixes.
Always back up your site before making configuration changes.
