You can include the Elasticsearch engine in your Magento 2 (Adobe Commerce) web store with the help of the Magento 2 Elasticsearch extension. The elastic search engine is a highly scalable and open-source full-text search engine.
It enables quick storage, searching, and analysis of large volumes of data. Also, it is a fast search engine that instantly displays the results of the given query.
Note: Elastic Search Engine v7.6 must be set up and functioning on the system before installing the Magento 2 Elastic search module.
Watch the video tutorial below to understand the extension workflow:
Features of Magento 2 Elasticsearch
- The elastic search engine can quickly replace the function of the MySQL search engine.
- The elastic server’s admin can easily update the data for products, categories, and CMS pages on the server.
- The index type determines how the data is saved on the elastic server.
- The admin will use a command line program to update website data on the elastic server.
- The Frontend’s search type can be adjusted by the Admin to either Multi-Match Query or Simple Match Query.
- Customers can search data by name, SKU, description, and a product short description if Multi-Match Query has been chosen as the search type.

- The spell-checking feature in the Magento 2 Elasticsearch plugin allows the search engine to rectify keywords even when they are entered improperly.

Language Translation
For translating the module language, navigate through src/app/code/Webkul/ElasticSearch/i18n and edit the en_US.csv file. Thereafter, rename the CSV as “en_SA.csv” and translate all right side content after the comma in the Arabic language. After editing the CSV, save it.
Now, upload it to the path src/app/code/Webkul/ElasticSearch/i18n where the installation of Magento 2 is on the server. The module translates into the Arabic Language. It supports both RTL and LTR languages.
The user can edit the CSV like the image below.

Magento 2 Elasticsearch Did You mean
When a customer enters the wrong product name, it will recommend all nearby products with the same product name to the customers.

Spell Correction in Search
The Elastic Search Engine will automatically correct keywords when they wrote incorrectly by the customer if the spell check is set to Level 1 or Level 2 by the admin.
Select Search Filters
There are four types of search filters to modify the search term provided by the customer. The admin can select the token filters.
- Synonym Filter
The admin has to navigate through Marketing > Search Synonyms.
Admin can create a new synonym group from here. For example, the admin has added synonyms for jeans and pants.
Now, the search engine will display all the results connected to any of these keywords if the customer searches for one of them.
2. Elision Filter- An elisions-removing token filter. For example, “L’avion” (the plane) will be parsed as “avion” (plane).
3. Lowercase Filter– A lowercase token filter that converts token text to lowercase.
4. Stop Word Filter– Stop words are removed from the search query. Examples of stop words are and, is, and to.

Select Language Stemmer

Select Character Search Filters in Magento 2 Elasticsearch
There are three types of character filters. That is used to remove unwanted characters from the search input.
- HTML strip char filter– The HTML strip character filter strips off the HTML parts.
- Mapping Filter– The mapping filter is used to swap out the mapping keys with values. So, it will eliminate any character from the mapping in the Magento 2 Elasticsearch module.
- Pattern Replace Filter– The Pattern Replace Filter functions similarly to the Mapping Filter. The main difference is that it’s used to replace patterns instead of mapping them. To replace characters, it makes use of a regular expression
To learn more about the character filters, please go through the following URL:
https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-charfilters.html
Index Management of Magento 2 Elasticsearch
Moreover, the admin can navigate through elastic search > index management.
The admin can change the status of the index type. For the index type, the admin has two options: update on save mode or update on a schedule. For example, the admin must change the status of a product index type whenever he adds a new product.
So, the admin can also use the system command line features if they have to change a large amount of data.
