Magento 2 Indexer / Reindex Usages through Command Line
Magento 2 Indexer/Reindex is a process that updates the search index for products, categories, and other data on your Magento 2 store. The index is a database that contains all the data related to your store’s products, categories, prices, and other information that helps your store’s search engine work efficiently.
The indexer is an essential part of your Magento 2 store, as it updates the search index when changes occur in your store. This process is required to ensure that your customers can find the products they want when they use the search bar or browse your store’s categories.
The Magento 2 indexer runs in the background and updates the search index for all the data stored in your Magento 2 store. It ensures that the search results for your store’s products are accurate and up-to-date. By default, Magento 2 has 13 indexers responsible for indexing various data types such as product prices, categories, and more.
In this article, we will discuss, how Indexer / Reindex works through the command line.
Show All Reindex Usages
To show all the reindex usages then open the terminal and in your Magento root directory, run the following command:
php bin/magento indexer --help
Output

How to Reindex Data
Run the following command to reindex the data of your Magento 2 store.
php bin/magento indexer:reindex
How to Reset indexer status to invalid
The purpose of resetting an indexer is to prepare it for reindexing. Sometimes, an indexer can become stuck in a processing state, which can cause issues with your store’s performance. In such cases, resetting the indexer can help resolve the issue by clearing any data that may be causing the indexer to get stuck.
Run the following command to reset the indexer:
php bin/magento indexer:reset
How to Show Index Mode
You can show the current index mode for your Magento 2 store by using the following command:
php bin/magento indexer:show-mode
Output
Design Config Grid: Update on Save Customer Grid: Update on Save Category Products: Update on Save Product Categories: Update on Save Product Price: Update on Save Product EAV: Update on Save Catalog Search: Update on Save Stock: Update on Save Catalog Rule Product: Update on Save Catalog Product Rule: Update on Save
How to Set index mode type
You can set the index mode for your Magento 2 store by using the following command:
bin/magento indexer:set-mode
To set the index mode for your Magento 2 store, run the following command:
bin/magento indexer:set-mode <mode>
Replace <mode> with the index mode you want to set, which can be one of the following:
- realtime: This mode updates the index in real-time as changes are made to products, categories, or other data. This mode can cause performance issues in larger stores, as indexing can be resource-intensive.
- schedule: This mode updates the index on a set schedule, which can be configured in the Magento 2 Admin Panel. This mode is better suited for larger stores, as it reduces the impact on server resources.
- manual: This mode requires you to manually trigger the index update using the bin/magento indexer:reindex command. This mode is suitable for smaller stores with fewer products and categories.
For example, to set the index mode to “schedule”, you would run the following command:
bin/magento indexer:set-mode schedule
