Elasticsearch Configuration

Setup

// app/etc/env.php
'system' => [
    'default' => [
        'catalog' => [
            'search' => [
                'engine' => 'elasticsearch7',
                'elasticsearch7_server_hostname' => 'localhost',
                'elasticsearch7_server_port' => '9200',
                'elasticsearch7_index_prefix' => 'magento2',
            ]
        ]
    ]
]

Index Management

# Reindex all
bin/magento indexer:reindex

# Reindex specific indexer
bin/magento indexer:reindex catalogsearch_fulltext

# Index status
bin/magento indexer:status

# Reset indexer
bin/magento indexer:reset catalogsearch_fulltext

Database Indexing

Index Strategy
