After July 2021, the 2.3.x release line no longer received quality updates or user guide updates. PHP 7.3 reached end of support in December 2021, and Adobe Commerce 2.3.x reached end of support in September 2022. We strongly recommend upgrading to Adobe Commerce 2.4.x to help maintain PCI compliance.

MySQL is the default search engine used by Magento. By adjusting the Catalog Search configuration, you can control the behavior of the search operations and determine the size of valid query text and the display of search recommendations. By default, MySQL always has the EAV Indexer enabled. This feature improves indexing speed and restricts the indexer from use by third-party extensions.

MySQL Configuration

  1. On the Admin sidebar, go to Stores > Settings > Configuration.

  2. In the left panel, expand Catalog and choose Catalog underneath.

  3. Expand the Catalog Search section.

  4. Ensure that Search Engine is set to MySQL (default).

    If switching to MySQL, select that option. This affects the available fields.

  5. To limit the length and word count of search query text, set values for Minimal Query Length and Maximum Query Length.

    Important: The value set for this minimum and maximum range must be compatible with the corresponding range set in your MySQL search engine configurations. For example, if you set these values to 2 and 300 in Magento, update the corresponding values in your search engine.

  6. To limit the amount of popular search results to cache for faster responses, set an amount for Number of top search results to cache.

    The default value is 100. Entering a value of 0 caches all search terms and results when entered a second time.

  7. To limit the maximum number of search results to display for search autocomplete, set an amount for Autocomplete Limit.

    Restricting this amount increases performance of searches and reduces the displayed list size. The default value is 8.

  8. To display search suggestions, set Enable Search Suggestions to Yes.

    This displays additional configuration options.

    • For Search Suggestion Count, enter the number of suggestions to offer for each search term that returns no results. The default value is 2.

    • To display the number of search results for each suggested term, set Show Results Count for Each Suggestion to Yes.

  9. To offer search recommendations, set Enable Search Recommendations to Yes.

    This displays additional configuration options.

    • In the Search Recommendations Count field, enter the number of recommendations that you want to offer. The default value is 5.

    • To display the number of results for each recommendation, set Show Results Count for Each Recommendation to Yes.

  10. When complete, click Save Config.
