How to show multilingual search results if you are using Polylang plugin.
Polylang plugin gives the option to make your site multilingual. It has features to translate WooCommerce products, taxonomies, attributes and custom fields to an unlimited number of different languages and display these translations to the customers.
Multilingual search results available for both AJAX results box and search results page.
Note: make sure that all your translated products are indexed by the plugin. If you have any issues with showing translated products inside search results then please go to the plugin settings page and click the Reindex table button. But in most cases this synchronization proceeds automatically after any product changes.
When WooCommerce products have Polylang translation then they are available for displaying inside the plugin search results for corresponding language. AWS plugin shows results on currently active website language that can also be changed via Polylang language switcher.
